My favorite way to explore a city is by segway! You get a little bit of history from your tour guide. Most of them are locals so they also have great suggestions on where to dine, shop, and be entertained. The best part of the tour is the SEGWAY! After you've completed a short training session, you will be ready to zooom away!
I especially love that by having wheels for feet, you can cover ground faster so you see more than you would on a walking tour. It also helps that riding a segway makes you feel young as the wind breezes by your face and you practice figure eights :-)
If you have a moment, check out a segway tour in NOLA. You'll see the French Market, learn about the oldest bar in town a bit about the history of this amazing city.
