I've got an idea for you team 694 - offer a coat check service for attendees the price of which is one of those cans you seek - in advance! Get the tournament admin to rope off a section with "racks" (are hangers really needed ???
just pile 'em up) We'll just pop a can into a coat pocket and have a place to park it where it won't clutter up viewing stands OR pit areas. You could also get more cans than you can carry home.
Any preference for what should be inside those cans? (even if there is no coat check)
