The heat, the heat, the heat?
Personally I enjoy the heat. My wife thinks I am insane but I realy enjoy extream temps. During the summer months, especialy this year, I will leave around 11:30 and finish up about 14:00. I have no problems with dehydration since I carry 1gal of water with me and a sport drink. When the murcury passes 105F I have better rides. When I lived in Phoenix, AZ. riding when it was 115F was great because there would be not a soul out there. Never had to worry about going to fast or if there was some one coming the oppisite way. Then when I get home, make some grub, toss back a pint and relax.
