There are times when you think that you've had a bad day and then on your way home you see a homeless man carrying all his possessions on his back.  I realize that there are people you see that prefer that lifestyle, but there are others who just find themselves in situations where they don't have the means to exist under their own roof.  The increasing number of Americans that don't have a regular dwelling is a social, economical, and political issue that doesn't have an easy solution.  I've seen bumper stickers that read "Not all who wander are lost".  Some who wander are seeking shelter.  What are you seeking?
