Serious? Tackle Box is big and the deck at the back where the collapse happened is half as big again.
I question the number also, lets say 1 person equals a space on the floor of 2'x 2'= 4sq feet x 500 = 2000 sq feet unobstructed area. Now input chairs, tables, bar area, storage, bathrooms etc., double that maybe for a total of 4000 sq feet or 40 by 100. So, it's been a while since Iv'e been there, do those numbers jive?
