Good luck on the trip, I'd love to go sometime. I was in Welt last year. Its a great place but just down the road they have the classic museum

Definitely worth the trip (I thought it was better than Welt) and you will be disappointed if you miss it. Once a month they have meets outside the museum, if you time it right you should be able to join one.
