I've read that there are places in the US where "tiny houses" are being built for homeless people. I wonder how that is working out.

I have a friend who gives gift cards for fast food restaurants to homeless people. I wonder if they use them, sell them, or throw them away. I've also read that some fast food places don't like homeless people to eat there. (Local managers' decisions, not corporate policy, as far as I know.)

I donate to homeless shelters, food banks, etc., and often wonder what else I should/can do.
