1) What is the best mobile network as I would like to buy a US SIM for Iphone. Any suggestions on network or SIM only deals with lots of data?
2) If I am able to stay in one of the many churches along the route - is that typically a space on a floor where you place you sleeping mat etc?> I assume there will be toilet facilities normally too? Leaving a donation is expected (happy to do so)?
3) Ok to drink or store water from tap?
4) If leaving from West coast begin of Aug, with plan to camp, comfort level of sleeping bag needed for Rockies - would one at 4 degree celsius suffice?
1. Verizon has had the best coverage IME. Trouble is, it doesn't use GSM like the rest of the world. I'll let someone else chime in on best plans -- if you get a SIM to use with one of the wireless re-sellers, that might be a good deal.
2. Most churches I slept on the floor. Toilets were always available, and some had showers. Donations welcomed or expected, depending on the church.
3. Tap water is almost always safe to drink. There'll probably be signs where that's not true.
4. Depends on how cold you sleep. My wife enjoys a bag that's 15 degrees warmer than mine. I was happy to have a 20 degree (F) bag a couple nights. If the bag is big enough to fit you, all your clothes, and a hat, you might make it with a 4C (~40F) bag.
