It was sunny. But I was painting the inside. If I went out in the sun without a hat my melon would be blistered cuz I ain't got no hair. I don't know what your altitude is over there in Wyo, but here in the Duke city it's 5000' with no moisture. The UV will cook the best of them. Especially mid day in July. I bet even a California cool dude smurfer with a deluxe tan would burn.
What does this have to do with vintage bikes? Nothing I guess, but I ain't had nobody to talk to all day.
