Long's peak is closer, the road is better, and they have electricity way up
there ;o))

I just realized that!!!  See my other post.  I am at 5300 feet and the
pressure is 25.05 inches.  Does anyone know what the spark distance
correction should be.  I got 13.25 inches "here", but at see level is
should be something shorter.  I can't remember the best attempt but maybe
someone has already won it!!

I think it may be significant!!!  I'll have to try and find or extroplate
some charts.  If anyone has any altitude vs. arc length charts, let us
know!!  I'll also dig back through all emails to see if there are any winners.

BTW - This could also affect the results I got for some of the TSSP list
data too!!

Cheers,

	Terry
