I've done some Pink Jeep tours. I had a great time having someone who knew where to go to do all the driving. I love the scenery of Sedona and it's safer to have somone else driving than me oogling and almost running into someone. There are tours for everyone: niece easy tours and those in which the hummer goes up 3 verticle feet... and down.

About the one that has the 3 foot drops in the hummer... the ad says not to go if you have any back or neck trouble. I went anyway. I had an absolute blast and did spend more money on three visits to the chiropractor to get everything back in alignment. I don't regret it at all.
