I was a bit worried about you in Kentucky, but I knew the trackers are not great in there. The Bikecentennial riders back in the '70s would complain bitterly about that part of the course because of the steady stream of close passes by coal trucks. But I heard it's not like that any more.
The buttons on the SPOT are nice. I just used the "I need help" button and it works really well. Probably should have used the SOS button, but you never realize how bad things are when they slowly deteriorate.
That episode did make me think that an inreach might be nice. I was out of cellphone reach, and I don't know how well the local emergency response would respond to Spot calling them up. In some places they really don't.
