Fair comments on the longer courses, but I'd just like to say that, for
those of us with young families (1 and 4 in our case), the quality and
accessibility of the string course makes a huge difference to our enjoyment
of the day's event. At the November Classic, this was brilliant. Families
were allowed to park close to the string course, which made for a pleasant
atmosphere, and not too long a trek for tired kids afterwards.
Future events, please note!

Slight problem with Emit: AFAIK, you can't interogate the contol boxes to check
who has gone through. In principle, with SI you could reconstruct the event
fromthe boxes when everyone has gone home (in the highly unlikely event of the
computers going down).
The relevance of this is that we are planning to use SI for the forthcoming
Round Rotherham trail race - see details (and enter) on
http://www.hmarston.freeserve.co.uk/rhac/index.htm
SI is not ideal; boxes have to time out before being interrogated - but at
least they can be interrogated - to check for outstanding competitors.

The elite competitors have argued, and the IOF Mapping Committee has
acccepted, that 1:15,000 is necessary to get a good perspective on
route-choice issues for classic-distance orienteering. (See the Mapping
Committee pages on the IOF website.)
Even I (who runs courses about half the length of M21E) have been able to
appreciate the difference in "feel" between 1:15,000 and the increasingly
common 1:10,000.
The questions raised by this include:
1. How will the elite and potential elite competitors bridge the gap to
international classic-distance competition if, at home, most of the maps are
1:10,000?
2. Is there a tendency to use 1:10,000 to squeeze more detail in, even
though we are supposed to fieldwork "as if for 1:15,000"?

You can ask the shop to give you their Windows print driver to install on
your machine. Then, the colours generated by OCAD should have the proper
headers in the EPS file.
You still have to do a pre-test (I would use a small section of the map in
question, and add features with the colours not in that section of the map).
This also helps with bleeds and contrasts (particularly in those areas with
blue and green stripes) and blurring corrections (line thickness').

The "Fiery" is a print server, not the actual printer, and some times the
colour conversions by the Fiery from the EPS file to the printer differ from
the ideal, so do the test print.

Good outline. I use "error" diffusion on all of the printers I have (3 - HP
and Epson BJs, and HP laser) to give me the best results.

ie - your lines look thicker.
If you are going the BJ print original to "xerox" competitor maps, I
recommend that you use your printer manufacturer's paper, and the best
quality available.
For critical applications (like photo ready copy for those offset print
shops who haven't seen the need to go "modern"; and they do still exist), I
use Epson "Photo quality Glossy Film - S041072, about US$2 a sheet, or HP
Glossy Photographic paper - HP C5982A ~US$3 per sheet, the last time I got
some (1998).
One real problem with BJ inks is that they fade when exposed to light. On
the less expensive "paper" papers, subdued room light takes about 1 year
before you can see a difference; normal summer sun (we are at 49 degrees
north, here), about 2 months.
The plastic films fare far better. But if you have a "master" print, don't
display it. Keep it out of the light. Then it should last beyond the useful
life of the map.

<<Here in Britain we have had a great deal of self congratulations about how
successful the WOC '99 was. But how do you measure success..........?>>
At the end of the day an event should at least cover it's cost if it is to
be seen as successful, I've heard murmurs that WOC '99 is going to show a
deficit of at least 28000 GBP (that's around 45000 USD!).
At least this deficit will be picked up by BOF funds.......>>
There are always murmurs, and rumours. I'll wait for the facts.
As to how success is measured, that is a good question, and from reading
Compass Sport obviously one that even our top athletes are not totally
agreed on. It was interesting to read in how one wote "WOC99 rates amongst
the best organised races I've been to", whilst another wrote: "The WOC
organisation was not up to the standard that is customary at major events in
Scandinavia", even though the Scandinavians can get it wrong, witness this
year's Nordic Championships. Pity the poor volunteers organising these
events. Yes, somethings did go wrong, and we all need to learn from them,
but some things went very, very right.
I'm sure that at least one measure of success will be that the Scottish
6-day's entry was boosted by getting on for 50% by the presence of WOC.
As to the GBP 41000 for marketing. I understand that that is the top end of
the range recommended by the report discussed by Council (approved 11-1,
with 3 abstentions), and that there is Sport England (English Sports
Council) money already available to support this.

People who ride bicycles at night think about this a lot, and there is a
PWM voltage regulator designed for exactly this purpose. The bike folks
swear by it. It's available from the guy who designed it (Willie Hunt),
and it's quite small and lightweight. Details are available at:
