I made a number of trips to the restroom and every time there was a line for the stalls. Fortunately I didn't require a stall but the thought of standing in line to use a stall that had just been used by someone else was very gross to me.....
I agree, I could never take a dump there. I even had a table setup there. I was there from 7:30 to 6:15 and 7:30 to 4.
I would rather go squat out in the parking lot then take a dump at a gunshow!
