I attended the Sonoran Arthropod Studies Institute's Invertebrates in Education and Conservation Conference was held in Rio Rico, AZ July 2011. Rio Rico is located about an hour south of Tucson and just north of the Mexican border at Nogales.
Field trips were in various canyons and mountains nearby but some of the best viewing was around the hotel and on the tennis courts early in the morning.
