Stacie - Just as an FYI...if you have a special travel plan coming up you can consider renting a satellite phone. The SPOT is a good way to go - nice balance - but renting a satellite phone might also work - best of both worlds. Google satellite phone rental for where you are and you should find some good ideas. My plan - unlimited talk with texting (texting is free and can be accessed via the web:
http://www.globalstar.com/en/index.php?cid=5510 - is a pretty good one and I am not sure if it is still available. I pay about $60.00 a month for my plan on my satellite phone. I consider it, along with my cell phone and SPOT pretty good travel insurance since I would rather not be buzzard bait if I snap an ankle trying to get "the shot!"
I am not trying to push a satellite phone but think there might be some misconceptions - this is a coverage map for my provider:

America) as part of my plan so sometimes I carry my satellite phone into Canada (I live in Seattle) since there are no obscene roaming fees with it! And as a point of a technicality - there are a couple of satellite providers - Globalstar and Iridium - Iridium has been around longer but something to think about - with Globalstar you get a conventional area code + number phone number so anyone you know can just call you without much hassle -- with Iridium there is a much more complicated calling procedure. Also, my research - at the time I got mine about a year ago - was that Iridium was much more expensive.
A note on CB and FRS/GMRS radios -- they are alright for line of sight and like you said, CB radios might be nice to pass the time but over time they have become less popular. I do have one in the truck but use it mainly for trail runs and listening when on the interstate. Again, all IMHO and YMMV.
Travel safe!!
