Tarp "reservations"

This is our third year to attend and we’re really looking forward to it. Semi-noobie question:

When we get to the venue there are always tarps layed out, sort of reserving areas. When do people come in and lay those down? I’d like to come in early and “reserve” a space bringing our chairs and saving my bride the trouble, but don’t know when they let you in to do that.

Thanks in advance.

They hand out random numbers the night before each show at mid-night, then you line up in that order the next day (Friday at 10am, Saturday 9am and Sunday at 10am.)
If you can’t/don’t want be in line the night before to get a number you can just show up at doors and go in after the folks with numbers, though this will mean you will have to set up near the back.

Have fun :cheers
