Based on links I found through this
thread, I watched some interesting videos.
One is free on youtube, and follows different people who are on the road.
The other has a low rental cost ($1.99). It's...interesting. At times I thought it was funded and produced by Walmart, but after reading some of the reviews, I realized that it's meant to be a social commentary which does mostly a very, very good job of just portraying viewpoints without judgement. If it weren't for some kind of poorly chosen edited-in footage from other sources, I would never have guessed that maybe the film maker was going for social commentary and not just advertising for Walmart.
I found the rental process to be a bit quirky...but it was worth it.
Anyway, worth watching.
