Wow, 4 hour gigs died in the 90's and you are playing 730-1? I think I've played one show that was 4 hours since then and it was truly a shit gig. Everything here is 3 hours.
I avoid Halloween, New Years, Memorial day weekend, and July 4th stuff. Amateur hour. People who don't drink go drinking and are not skilled at drunk driving like regular drunks are. They tip like shit cause they aren't regulars, just self indulgent drunks on a one night bender, and there are tons of cops on the road who are no refusal blood drawing people with a judge up all night to sign the warrant on demand. The last couple new years dates I had were foul weather, and a waste of damn time. None for me unless the money is serious. Good luck alund.
