I have tickets for the ZZTop show this Saturday. What time does the parking lot open. I would like to get there early?

The parking lot opens 2 hours before the time of the event

I saw Dierks Bentley last weekend. Show started at 7pm, gate to enter was open at 5:30pm. Parking lot is open earlier.

A few hours before the first act

They usually let you in even earlier then that.

2 hours before the event begins
