After going down last fall I have promised myself ~~ and my wife ~~ that I will always ride with protective gear ~~ and I do. But that makes riding in the summer miserable in Fresno. My personal limit is 97 degrees. If it gets any hotter than that Ol' Bessy stays in the garage. Today it is supposed to be 108 ~~ tomorrow ~~ 109. It doesn't look like Ol' Bessy will be seeing much action for another week. For you ~~ how hot is too hot?
