Yeah, I lived in Chandler and Gilbert for a couple years and never had an issue there either.

Here in Mexico, everyone's house is surrounded by big fences with barbed or electric wire, etc. on top. The delivery guys could never actually get to a porch, so they return when you're home. Once I had a delivery guy call me and ask if he could leave it with the next door neighbor, and I said "sure!" even though I don't know them other than saying hi and bye as we pass. Worked out just fine.

Anything left on the street is fair game. I had my trash cans stolen on trash day twice before I just started leaving the bags out on the street.
