"7. In debriefing with the NPS incident commander he said they "always launch" on a Spot SOS signal, but do so reluctantly because they receive so many false alarms. One woman sent the Spot SOS signal because her water "tasted salty." So a Spot is a great tool to have, and will probably bring help, but use it responsibly."

This is a crucial point. Grand Canyon Nat'l Park is a hot spot for SAR within the National Park service - a combination of high volume visitation and forbidding terrain -please use responsibly. Some don't - the party triggering their SPOT for salty water did so for the third time in two days.

Thanks for the informative report.
