OK here is a TZ moment. Just tonight Karen was telling me about the conversations about doing a get together at an indoor water park. She remembered seeing Great Wolf Lodge in Sandusky and knew about the new place at Cedar Point. We has NO IDEA about that third place (but it sounds really cool). And in keeping the NY folks in mind we were looking for someplace half way between Chicago and New York.
Here is a another place in (of all places) Erie, PA.

From Albany (sorry can't spell schenechty) 5hr 43 min
From Chicago 6hr 38 min
From Detroit 3 hr 55 min
From Cleveland 1 hr 25 min (Erin hosts

)
What put the twinkle in my eye about this place is the indoor laser tag area (KNOCK KNOCK Cameron, Nick, Alex & Ryan, John, Gary, Mike, Tom, Bruce, Rich & Jeff - wanna come and play?)
Another 2cents for the pot, BUT I think this is closer to center for everyone concerned. Whatta think bout these apples?
