Hmm... I like the rivers idea. I was looking at bluffs but the fact that I had to look up the bluff names and elevations tells me most people aren't likely to know that off the top of their heads. LOL Probably most won't be able to put rivers in order of size but at least the names will be recognizable.

I had thought about town sizes but that could get confused with the person's location. Getting peoples' locations listed is on my to do list, actually. So not keen on using that.

Rivers, though... Yeah, that one has promise. I'll have to get a list of river names in the area and put a list together.

Thanks,
