having all those parks ~6 hours isn't a bad thing I can confirm, though by no means would i recommend anyone live where I am.Duncannon, Penn.
Loads of stuff within a 6 hour drive, which is possible in one sitting, and super close to Skyrush.
As much as I'd love to live near Steel Vengeance, it's too far from Toro and Boulderdash.
For the US I'll echo the Nashville sentiment, though if I was limited to just a city (and the parks associated with them) I'd say either Orlando or LA
