GDG Tucson is a place to learn about developing with Google services and technologies. It's also a great place to network with other developers. We usually host events monthly, but at least quarterly. Some are just one hour code talks, others are multi-day events (like Study Jams or I/O Extended). The events usually are held in the Innovation Space on the University of Arizona campus. All of our events are free to the public.
