Audiotomb,
A little off topic but the Tallamena Parkway is worth that trip on its own. I've ridden my motorcycle and driven it in my sports car on several occasions. It's kind of like a 30mi piece of the Blue Ridge Parkway on the edge of Arkansas and Oklahoma. Unfortunately, that's about all there is to do unless you head to northern Arkansas where you'll find more terrific roads.
Thanks to everyone who has responded so far. It sounds like we are all pretty much the same. A few hours or while out on business or vacation is the norm it looks like. I've auditioned pieces from San Francisco to NY, Minneapolis to Orlando myself, but only when I'm there for another reason, too. As I've moved to a more rural area, the nearest "city" has dwindled their offerings over the past decade for the high-end market. So I am envious of you who get to hear the latest and greatest in person. Often when I enter my zip in a dealer locator I get "no dealer in your area." Usually I'll put in a zip 4-6 hours from me and will sometimes get a hit, but not often.
So I've tinkered with the idea of opening a shop of my own, but then it dawns on me that there isn't the population to support it within 2 hours or so. Oh well. Just leaves more time for listening, what a shame.
