Barber's is a must see. Went to the New site for the first time in the early spring of this year, then went back in June to take my son. He was 1.5 years at the time, and loved every min of it. He just didn't understand why he couldn't climb up on the bikes like he does the ones in our garage. : ) The Porsche Experience was going on at the track and he sat there (windows in the back of the museum) for over 30mins wathcing them go round.
My brother just got a newbike and we are taking a trip this fall. Barber's is one of the way points already set.
