im on my side yard, in the middle of the city i live, and i will be on my little cramped sideyard with my bong, and piss in the storrm drain that is right there i piss in. its so refreshing, my neighbors window is right there, and they keep it closed cause they know im smoookin, and i wash all the piss off my concrete (if there is any) with my bong water into the drain, and it is clean dry the next day. lol, its been working for like 3 years. like 3 times a week.
