I'm not telling you what's going to be in there yet, but I think you'll like it.
If you visit it, though, you might want to touch the panels. You can make them raise and lower! (And boy, let me tell you from having spent a number of years dealing out of canvas tents at the Pennsic Wars; being able to raise and lower tent panels with a touch is really something!)
While you're there, take a look around the island. The last of the snow is expected to melt tomorrow, and the red maples are in full bloom. With any luck, there will be some Spring Beauties by Valentine's Day!
