This seems hugely subjective. Personally, I felt extremely awkward having put a 4 million dollar aircraft and 3 lives at risk to come bail me out because I didn't want to sit on a sandbar for who knows how long (and even then I wasn't sure if anyone would be willing to carry my stuff out).

The SAR guys assured me they rather enjoyed the practice. I was very impressed with these fellows.

I wouldn't do anything I wouldn't ordinarily do is the bottom line for me. The thought never even occurred to me that I would need SPOT for anything other than sending "I'm OK" messages. Now I want to be able to call a floatplane if need be instead of SAR.
