Always try for long pants, boots, gloves, full face, long sleeve t-shirt and usually mesh or leather jacket.
Having said that, have you ever been in Memphis in August at a stop light? CHIT!!! In August, for short rides I'll sometimes go to a half helmet, drop the jacket, forget the gloves and wear a ss t-shirt. Am comfortable but feel stupid, [highlight]I knows what be smerter[/highlight].
In fact, leaving Wednesday for the state HOG rally in Bristol, TN, about 500 miles away. Temps are to be around 100 so I just decided to put Bessy and Girty in the trailer and I'll cruise along in the air conditioned cage. In fact, my trailer holds 4 bikes and I'll bet by the time I get there, a couple of friends will have whimped out and joined me.
