Can't remember ever doing that. If I'm bringing PA, I'll show up 2 hours ahead. If it's just my bass stuff, 1 to 1 1/2 hours. I do like to pack up and load out promptly, but depending on the venue, I've been known to hang around afterwards and have a drink with the management. Altogether that might mean arriving at 7 or so and staying till 1 am, which makes it a 6-hour night, plus whatever the drive is.
