Over ten years ago, when the bandshell (tent) was new and maintenance had not yet become familiar with setting it up, a lot of rain fell and the tent collected water and begin to sag. The problem was two-fold: (1) if they left the water in it, the very-expensive tent would tear under the pressure, but (2) whoever was unlucky enough to pull down one side of the tent to drain off the water would likely drown. :shock:
I don't remember how the situation was resolved. But it was the talk of the town.
