Wagon Wheels Invade Boise!

They're everywhere! I started thinking I would snap photos of wagon wheels as yard art whenever I just happened to see them, and now I'm noticing how prevalent they are. Are they common in your town? This one is positioned near an old cart of some sort. I was wondering aloud where people got them, and why they decided to put them in their yards - and my kindergarten daughter said, "Maybe they keep weeds away." Hmm - maybe! More wagon wheels here, and here. Boise is along the Oregon Trail, that could be part of the inspiration.
