Years ago, it was whenever folks with banging heads rolled out of bed and cranked up their rusty 4-wheel drive vehicles, or were able to pedal a bike or pull a wagon full of kids. When you heard horns honking, you knew it was time to find your bathing suit, grab a beer, and find your keys. After a few passes around town, the mechanized part of the procession would head on over to Seaside to collide with their uppity parade. It was a clash of the haves and have nots.
The last couple of years at Grayton, it has started around 8 am, lining up at the Red Bar and looping around town, with shinier vehicles and shinier people, almost all of whom are now haves. Having a definite start time is the first sign that it is all downhill from here. The people, their dogs, and their conveyances are decorated, but nothing like a real parade with floats.

I have only glimpsed the Seaside parade, years ago during the aforementioned clash. It is more elaborate with decorated floats and an absence of rust.
I have not seen the Rosemary parade, but am certain this guy is not in it:
