Maybe. For the entire time I did solo backpacking in the Rockies, electronic signalling devices were not available. I was therefore prepared to spend a period of time awaiting rescue, and there were rock solid people who would report to park staff if I did not check in on schedule.

Edit: It's a fair comment. I were doing it now, I would certainly look at the options available, as long as they were completely non-invasive as I pursue my immersive walking meditation. Zero tolerance for a cell phone bleeping nonsense.
