Good story, @
CrankyOne.
It's an interesting point about how being upright reduces sweating. I hadn't thought of that.
I have noticed how cooling linen trousers can be. I ought to get a pair or two this summer. I used to wear them, but they don't last long.
I disagree about rolled up sleeves. I've paid attention, and they are cooler than sleeves that are down.
Now you got me interested in trying upright riding again. I have a Raleigh Twenty that needs some work before I can ride it again.
