Future of our hobby ?

Yesterday we had our annual Mopar club picnic. As I looked around I started to wonder. In our club there are more old cars then the new stuff, but the new is slowly creeping up in numbers. Among all of us with the Old cars, I am the youngest one at 33. Anybody my age or younger has nothing but the new cars. I am trying to keep my son interested in the old cars, he's into it so far. BUT ... what I see happening is when he's old enough to drive and really get in the car hobby our old cars will be obsolete. Seems like all of the old car owners are the "older" people, when someone comes up and asks about my '70 swinger they act surprised to find out it belongs to me ! What do you guys think ? Will the old cars go back to dirt cheap, nobody wants them prices ? Do you think there is enough interest in the younger crowd to really keep these cars alive ???
