I just found out I'm working a one day temp job at a construction site tomorrow. At jobs like that, there's often not a bathroom on site, so guys just go pee in the bushes. I hate to pretend that I have to take a dump and walk way back in the woods and squat every time I need to pee. I need some emergency STP ideas. Medicine spoon doesn't work for me, it doesn't seal properly. I'm thinking something soft that can fit in my pocket, but it would have to be something I can buy at the store and modify myself since I need it for tomorrow...
