Stacie, I just got back from 2 weeks in the Southwest. Sunny Day always has her tags, but I also keep her Vet records. I've only been asked for them once and that was from a vet when Sunny was sick--yes, that can happen.
If you have an iPhone, I used 3 apps on my two week trip to the Southwest.
Campwhere shows state and city parks, along with BLM. Loved the app. Valley of Fires in NM was a BLM with paved sites, electric, hot showers for only $18 per night. Magnificent area, great views and good info as to how the lava got there, and a walking path thru the lava. I would never have looked for the site without the app. I was looking for a site near Riodosa at a lower altitude, and I found it.
Allstays shows all campgrounds. A small mom and pop RV campground outside of Joplin, MO that was quiet, clean restrooms, hot showers, electric for $17 per night. That and my teardrop was all I needed for a last night on the road.
iExit shows what is at each exit--food, gas, other things.
