Leave your cars home...just go an walk around.
I have shown cars for over 15 years in this are, and the Hatboro show is a circus.
For those that want their vehicles judged, the organizers "look" at each car as they are registered and then decide if they want to really judge that car or not.
For those that see it as a cruise night...be prepared to babysit all night, as the cars are tightly backed....with folks walking dogs (metal leashes), pushing strollers, wild kids...IMHO....too much potential for damage or problems. Plus, unless you get there very early, you will wind up parked at the end of town where there are no street lights.
There's a good cruise night the second Saturday of each month in Harleysville PA, at the Wal-Mart....well controlled and a good turnout.
