There's a yahoo group dedicated to the circus train.

Train! Did I miss it!? I must have fallen asleep under the bridge. 8)

That would be a great idea for a car chassis design to get attention....a locaomotive design, complete with the big wheels!

Don't forget a trailer "Caboose" for your daughter BIPS :D

Hey, now, we don't want anybody talking about his daughter's caboose around here! Least of all the teenage boys!
