Who are you kidding a pop bottle would work for you.I was once doing a trip from Indianapolis to Lincoln and about halfway though missouri, in the middle of it ******* no where, I had to piss. Didn’t want to find a stop and possibly end up in a scene from Deliverance, so I went in a Gatorade bottle. Obviously bigger than a pop bottle, but I still ended up pissing all over myself. 4/10
