I agree. I can bike easier in the high 90s than hiking, especially with a pack. But Machka was talking about the 40s, which I believe translates to the 100sF, so I wonder if some people have a special ability to sweat out 98F body heat into 100+F air. How dry does the air have to be in the hundreds to evaporate sweat?
