Puzzles!

Many campgrounds have a room that have tables set up with puzzles on them.

But this is the first one I've seen that has a puzzle tray storage system!

On the top are the boxes with the pictures for each puzzle by number. The trays are numbered. So, you can take out a tray for the puzzle you want to work on and put it on a table to work on it. But, when other events are going on in the room, the puzzles can be put away and the tables used for other events! How clever!
