I went to this show last month and it was worth the trip. There are a lot of high end cars (4 maclaren's last time) along with the usual mustangs, vette's etc. Last month there was one other Boss, a few classic mustangs. It starts at 8 and people started heading out after 10. I'll be there again Sunday morning.
