The commute home yesterday was pretty warm- mid 90s I think- and I was wondering if just the one water bottle would be adequate for the 17 mile ride. At about mile 4 I had already drunk about half my water. I passed by a guy watering his lawn and yelled out, "It's hot- spray me!" He said, "Really?" I said, "Yeah!" So he hosed me down pretty good as I went by. Nothing like the power of evaporative cooling; I felt almost cold for the next 5 miles.
