Arizona Highways is indeed banned by the Arizona Department of Corrections. The reason? It contains “content that depicts, encourages or describes methods of escape and/or eluding capture, or contains blueprints, drawings, road maps of Arizona [or] areas contiguous to Arizona.”
I always thought of Arizona Highways Magazine as a different form of escapism. DoC should instead ban publications like Arizona Capitol Times which reads like a recipe book for how to commit white collar crime!
