is there adequate parking for 15 classic cars on a Sunday afternoon?

Out front on the main street, not really, but there are side streets

Down the hill from Mel's is a large public parking lot. Its about a block away but it's always empty. Not good signage so just go down the hill about a block and it's on the left.

If you get there early there is parking on top of the levee.

1 block away is a lot

Not right in front of the shop. You could park on side streets near by.

No

Not much parking

I believe so
