Also, JPK, your insight on knowing about ALL the possible rescue/response/medical options in a particular area is a damn good one. For example, next time I ride in Colorado, I'll be looking up the fire stations, ranger stations, etc. as well as local hospitals beforehand. The idea that one's own GPS is a wealth of local medical resources is a good thing to remember, as well.
Excellent to coordinate parallel rescue efforts that turned out to be faster than the SPOT/local agency response could be; I can see why the seeming lack of response was upsetting in the first place, though. Sometimes good old fashioned first aid and legwork are the way to go.
It's easy to start to have expectations that we're owed a fast, coordinated rescue if we have SPOT devices and cell phones, these days. In reality, we've bought a service from a private company, but it's still one or more public agencies (likely underfunded and understaffed) that end up doing rescues. The SPOT is just one more tool that might help in a tough situation.
