I like plastic bags. They fit my kitchen trash can. Sometimes, when the bags run low, I go to the supermarket and buy some items and bag them myself. You would be surprized at how many bags it takes to bring home the groceries.
I use those little bags for everything.
Let's see:
-to wrap chicken bones in and bury deep in the trash can to keep out nosey dogs.
-wrap meat so it doesn't leak after bringing home from the grocery.
-great to put dog poo in/also "scoops" of litter pan stuff.
-use as lining for all small trash cans in the house.
-if going to several different places with items to be delivered, these little bags are great.
And don't buy that they don't decompose. Myself runs a fine and steaming compost pile and if one of these little bags makes it into my pile...it ROTS. Sure, it takes a little longer but ladies and gems...those bags ROT. They're made out of a petroleum product after all, which also comes out of the ground. Or, for those who still don't believe, do you notice the world is not overrun with those little bags?
If after all my uses, I still have a pile of those little bags left, I bundle them up and take them to the grocery to be recycled!
Damn, San Fran....get a grip!
