I use all those grocery bags for the cat litter, the dog crap, and to line all the bathroom trash cans. I still have more than I can use though. I often turn down bags at gas stations, liquor stores, or the grocery store if I didn't have a cart to start with. People might think I'm being environmentally conscious, but I just already have too many bags. However, when I have torn bags that I can't use, I at least take the time to tie them in a knot before I throw them away because I don't like seeing them stuck in trees and fences and stuff.
