If I were you, I'd plan my visit so you could take in at least a day or two of Pinball Expo in Chicago as well :)
JWJ - I would love to - but not this trip.
If I handle this Ok I am thinking about going back another time for a bit more 'pinball related' action - so maybe then.
Might crash your place - that's the Aussie way
And Cavey I have been to Six Flags twice ,years ago- it was a great park then and I know it has improved a LOT, we were the first to ride The Ninja when it was one of the first 'underhanging' RC's , but it was very 'ordinary'
I am definitely planning to take the kids there, but VERY unfortunatley I am no longer able to ride Rollercoasters and it P*SSES me OFF large
Man O Man what I would give to ride X or X2 !
