Tri Girl, you made me laugh with your "armpit of AZ" comment.
Glad to hear even the natives say that.

One time, on the way back from San Diego, we stopped in Yuma to eat lunch. We were outside at a Jack in the Box and this homeless guy came up to our table, begging food. When we ignored him, he yelled, "Anybody home?" Finally, my 4 year old gave him food.
"Anybody home?" became a family joke.
I have been to the Canyon once, and it sure wasn't hiking! The teachers I worked with at one time did a hiking trip there, every spring break, but I was always afraid I would have to call that helicopter and get charged $1200.00 for a rescue.
