I was a bit late to the party this year but there were a few things that stood out.
There were a lot of people. That's a good sign that there is pent-up buying out there. 
Though one had to look for them, there were some really great products that I had never seen before. Anyone see the all titanium exhaust systems coming out of the old Eastern Block aircraft companies? I had to wipe the drool from my chin after seeing the craftsmanship, but most people just walked right on by, myself included the first time.
Some builds were the same way. I watched lot of people walk right by, but to be able to talk to the owner and the builder is great. It's an awesome car.
 
It's a real 1930 Cadillac on a Heidt's chassis powered by an LSA. There are three different custom machined rim sizes (fronts, rears, and two spares.) There's a flower holder on the dash. The interior and rumble seat is incredible. The smell of the leather.....
In the end being able to put a face to the name is great. Too often we never get the chance to do that.
