As for bad smells, I remember when I was little we had this trash can that had filled up with rain water and stagnated.
Lol, funny you should mention that... I once stepped on some awful-smelling dog-doo on a turf field (don't ask me why it was there) and I was having trouble getting it off, so I looked around and found a trash can filled with rainwater from the night before. Never been so happy to stick my foot in a trash can... =P
