[pct-l] Emergency Devices

[Kevin Cook]

All this talk about the Spot got me looking at it. I'm interested, but it
seems a bit expensive. There seem to be several subscriptions to along with
it. I'm pretty tech savvy and all, but I wasn't quite sure which service(s)
I would want on a thru hike? I like the idea of sending the "OK" message
each day, and having people able to track my progress would be neat too. ;)
