Niiice! That yellow 37 has come in to my shop once, and that purple/pink Chevy (that you snapped pics of the hood) is my buddy's dads. Lil 454 under the hood. Seesko, wherebouts in plymouth are you? I haven't seen you in my neck of the woods so I'm guessin your on the east side of 169.
It's hard to say. 50 to 75. I had to park across the street. It gets pretty busy. A lot of variety for a weekley show. Good food too.
