I met fellow PC patients at the cancer center here in Fla. One guy, and his wife, moved down to Fl. for several months from a northern state where proton was not available. They could have gone to a nearer facility in another state but they chose Fla. They rented a condo near the beach and had an unexpected vacation while he had proton treatments.

Some provinces will pay to send patients to the few U.S. clinics that have it, but from what I've read, they generally prioritise pediatric cases (especially if the cancer is near the brain), since the main benefit of proton beam is a modest reduction in side-effects, not an improvement in overall survival.
