Thanks for writing. At the moment we don't have a lot of content geared toward the Southwest on BHG.com, but we are working on it (please be patient while we do this!).
In the meantime, I might refer you to the City of Tucson --- they have some great classes and the information will be geared specifically to your area, not just your region. Learn more:
