Hey, that's not a bad idea! Indians didn't have garbage cans, and I wasn't creative enough to improvise. =)
The Indians wouldn't have built a city in a swamp either, and even if their ti-pi's blew away, they'd just run a heard of buffalo over a cliff and make new ones.
I don't know why the didn't use a buffalo hide for their smoke signals though, sleeping on that stinky, (and valuable) blanket after couldn't have been pleasant.
