My friend Brant has a whole Facebook album devoted to porta potties. Really. Me, I am not fascinated and I have no problem going behind a bush. However, most of the riding I do is not that rural. There are lots of porta potties around here. However, there is one playground in Acton that is no longer used for baseball and last year they did not put the porta potty there. This was a stop on our bike rally ride... we called the town and they brought it out. It's not back yet this year, though.
I limit my coffee on days that i have a long ride. Usually I pee every hour, all morning, and obviously, can't do that on a ride. However, as I said before, something happens to my body on long rides. Yesterday, I rode for over 3 hours, almost 50 miles and I only went once, at the lunch stop. I barely went when I got back. I am not dehydrated, it's clear and all that, but it takes about 2 hours after I get home, and then I start going more. It's like my system shuts down.
