Clubs are good.. you should find one!
and based on your love for several marques (and older cars), I'd recommend a local AACA club...
and yes, I agree.. If I'd been driving the dodge truck at a Camaro event, I'd have parked at the back..
Note: I've driven Corvettes to Porsche club road tours, and I always get on the back.. (but when we stop for lunch, I tell them it's so I can pick up the parts that fall off from the porsches...
)
