I learned a trick from Amy W. at Bonnaroo. She had a very convenient pop up trash can that we used all week. It came from an outdoor store and I thin is used for leaves and stuff, but what an AHA use ..to turn it into traveling trashcans! This is something we have ALWAYS needed when tailgating. Target has some now that are the perfect Titans Colors!
They are most easy to find this time of year, because of all the back to college stuff that is out. You can also buy several different colors to separate your recylcings from trash.
