Just talked to my friend about going to this show. I've gone the last 5 or 6 years and always enjoy the old iron. There's bikes there I've never heard of before plus alot of parts. http://www.rhinebecknationalmeet.com/
Went to the Harley dealer yesterday, must have seen 100 bikes in the parking lot. Only one other Evo, no Shovels, the rest almost all newer Twin Cams, most of them not even 5 years old.
I had a buddy years ago that had an Ariel Square Four. I saw him a few years ago and he still has it. Pretty neat old bike. I do not remember what year it was.
