Racing in the Fall is the best , the Springs not bad, but racing in the Summer is my least favorite. Especially in a car with a black vinyl roof and black interior. I moved down a class so I don`t have to wear a fire jacket anymore, in the summer I wear shorts and pull on a pair of sweatpants just before I get in the car for a run and take them right off as soon as I get out. Racing in the Summer can be draining but when you race for Points like I do you learn to deal with it. I also have a small fan in the car that helps a little.
