My one "problem" job is a patio where I have a patio in front (400 seats), waiting ares to the right and left with bar service
and a terrace area directly behind me, wrapped around a pool with beverage service.
It takes three heads, 6 cabinets and a powered monitor, not for volume, but for coverage.
The restaurant is in an old farmhouse, so there is no room for storing anything. It's 4 trips to the van for two of us; both in and out.
I'm working on a 4 nighter where the equipment stays...rare these days, but way better for the back and nerves.
Many of my jobs are just what Dave describes. Luckily, my son/bass player often sets up for me when I'm finishing another job. I just come in and play!
