Out here in CA, the Bills games start at 10 AM.
When Bethlehem Steel was open, they bars nearby would open at 7 AM for the night workers.
When I was young, I worked at a Denny's. On a St.Pat's Day had to work 3rd shift, After putting up with all the drunks all night, we went to Como Park. One of the people had a couple of six-packs of Genny Cream. Were sitting there drinking while the park workers came by to pick up the garbage. They asked what we were doing there. We explained ,offered them a beer and finished off the beer about 10 AM
