I use this site
http://wahiduddin.net/calc/calc_da.htm
and Weather Underground
http://www.wunderground.com
to get all the info. You can view the conditions on past days on Weather Underground as far back as the beginning of the year (at least).

You will need to know you elevation as well. Not a problem for me since I work w/ GPS every day. :)

Man you guys are lucky. I'm about 100 ft above sea level and the best air I had all year was a pathetic 1640+ feet.

I'd love to make a pass in air like that :eek2:

HOW about it. Now there is 5-6 inches of snow on the ground. Our local track stays open just about all year long ,on sunday only if the temperature is 40 degrees or warmer on that day.

and think my TA ran 12.84 in -285 hmmmm
