Most of my rides are in the 4 hour range and at 75 I am most likely going to need a nature break at some point. Since this is farm country I can usually stop anywhere I need to, but at this time of year the corn is just starting to germinate so my options are limited. Not a lot of public restrooms around, so I plan ahead to stop at the one or two wooded areas on whichever ride I am doing even if I don't really need to. I try to get out of sight and have not had any problems with passersby but expect I could get yelled at if one of them should be the landowner.
