I can tell you that Bixby has aleady been to one of "the great places," that being GC: Nocturnal where I picked him up. It's part of a mega-multi challenge in central PA, and this cache involves a 4-stage, 4 mile hike, and has to be done at night!
My husband is a pilot, so we should be able to get him to some "high heights." I can either move him along after that, or if you don't mind my holding on to him till December, I'm taking a trip to NYC on the 12th. He'd certainly see some great sights there. Your call, though, because that would leave him idle for 2 months (other than tagging along on my caching adventures).
