Oh, now you're giving me flashbacks to a spring Best of the Northwest art show at Magnuson Park in Seattle. The park is a former naval air station, and the show was in a quonset hut/hangar with serious roof problems. Spring in the Northwest is the rainiest of rainy seasons. New leaks would spring up over night (one right over a booth, destroying her fabric bags), and fearless teenagers on a scissors lift would roam the aisles between booths (at full height), hanging drop cloth channels to aqueduct the water off to the sides and down to a floor drain.

So I guess the thing you wouldn't expect is that rain can be an issue, even at an indoor show?
