I have a couple routes with planned stops just in case. My 10 mile route is an out and back that has a portapot at the 1/2 way point. I also do a lot of routes out to a hotel nearby that never bitches when I use their bathroom. And I know where several other construction portapots are. If I havent taken care of things before I leave the house in the morning, I always plan my route accordingly. Going home would be ok too, but I am afraid of waking up my kids.
