I've joined up with caravan 2W at Walker Lake in Nevada. Been here a few days. Important things to note:
Get Verizon. No one else can get a signal - me included!
In Hawthorne, the closest town, McDonald's and the Safeway grocery store both have free, unsecured WiFi. This has been a lifesaver! I message me family and friends via Facebook messenger to keep everyone updated and from freaking out and coming looking for me.
It gets hot fast in the day & cold just as fast at night. Be ready for huge temperature swings. Don't push yourself if it's hot. Slow down, take breaks and drink a lot of water!
The "major sheep crossing" signs are there for a reason! It's normal to see dozens of wild mountain sheep near or on the road most of the times you drive through these areas. Time of day doesn't seem to be a factor.
Refill your water jugs at Safeway for $0.40 a gallon.
My favorite thing so far, aside from walkin up to an amazing view, is having other caravanners with me. So glad I didn't try to do this on my own my first time out! If you break down, faint, have your tent try to blow away, or just need some conversation, they are there for you.
I thought I was going to crave complete solitude, but I found out I'm not that much of an introvert!
Plus, they are very relaxed about the whole thing. If you want to be left alone, set up a bit farther away and no one will bug you!
