Spartan2,

I agree with you about people relying receiving the "OK" messages. I soloed Quetico L. a few years ago and had my parents and girlfriend at the time on the receiving list. Both said they were antsy if they didn't receive a message in the evening (when I planned to send them). Interestingly, they were also the folks who insisted that I buy it and use it. I don't think they had the right mindset to begin with.

If I solo again I'll probably carry the SPOT with me again but I'll try to lay down the law about not counting on receiving a message.

My whole take on it is, if it helps you or the folks at home feel more secure, bring it.
