Check out the Black Rapid over the shoulder strap
Just on the outskirts of Tucson you have Sabino Canyon.
You have the option to take a truck ride into the giraffe and Rhino pens. This will also allow you to hand feed the giraffes. I did this last year and it was great.
Not sure if this relates, but had problem with Picasa not putting photos in correct date. I had to set Picasa to verify compatibility. This cured the problem.
