Glad someone asked this because I was wondering myself. It's pretty warm here in florida too but usually the humidity isn't TOO bad, unless it just rained. I haven't ridden in the 'hot' months for a long time so when it started to warm up this year, and I'm riding, I was just MISERABLE. I work in the A/C all day, A/C at home at night so I wasn't used to the heat. My friend and I were joking about riding in bathing suits! So far I seem to be 'adapting' to the warmer weather pretty good. No more soda at the barn for me though, it's water or vitamin water...or juice with a lot of ice. I know it's just me because the horses don't sweat much, then again the horses that I am working with are not really trained so it's a lot of work for me and not much for them!
