Bring a 5 gallon bucket and heavy duty non leak garbage bags for shitting outside the house. For pissing, drill a hole just short of breaking through by a couple of inches. Keeps the place from looking like a shit hole of piss yellow all over. Do the same for things like sausage water.
as far as i can tell after picking up trash on 6 mile bay most guys leave there shit bags on the ice, the more overnight ice castles the more garbage left on the ice. from shit bags to ice holes used as coolers and left full of frozen beer.
