my ride to work

becasue of the ever increasing gas prices, i drive a motorcycle to work everyday. this is not that bad, i like to ride and all, but 80 miles round trip sucks. sucks more when i am getting 13 mpg (at 65 mph), and less when i get 37 mpg (at 90 mph). well it is starting to get cold in the morning, and i am definatly prepared for the cold but i have discovered a geological oddity. maybe not so odd, but strange to me. i start off in canton, ga and it is about 60 degrees... not that bad, warm enough if you have a jacket with a liner and some leather gloves. here i am cruising at about 80-90 mph, and i go through jasper (the next town north) and things are still the same. as soon as i get out of jasper, and go around this turn, the temperature drops at least 10 degrees, and is freezing. almost like i hit a wall of cold, and the rest of the ride is freezing. it really sucks, because here i am enjoying my semi-warm weather and boom, freezing. now there is a bit of a dip in the road there, not a valley per say, but i guess it is considerable enough to constitue a 10 degree drop. it's interesting to me at least, even if it does suck. i wonder how far i will make it untill i stop riding the bike to work, i do have a suit that is designed for 30 below, and with the wind chill at 90 mph i will be there soon. i will let y'all know.
