For yard sale day, what is the earliest shoppers can come? is there any issue with parking for shoppers before a certain time?

Plenty of parking there no problem with that I think everyone starts around 7 a.m.

Opens at 8 grassy field for parking gets a little dusty

I think it opens at 8 AM. Plenty of parking

With parking, I use the far grassy lot. It's a lot more flexible.

I think 8am but check the website for sure. As for parking... earlier the better for a good spot!!
