Scotty, I would always suggest a demo ride. The other thing I would suggest is that if you get an HT, that you stay very attuned to the area that you're gliding over. Although the glide is very intuitive, you still are more of an active participant in it than you are, even, in a car.
Check the search feature and see if there's anyone near you in Ohio. Maybe you could email them and work out a demo ride. Or... go to the Segway page

and look up the name of the dealer in OH. I don't know if they're anywhere near you, but you're one of the few states with a dealer.
Good luck!
