Courtney, what an exciting and neat plan.
Perhaps you'll find opportunities to do your freelance sign interpretation wherever you are.
Good your husband's field can be done wherever.
We never full-timed, but traveled a LOT with our 2 children, and they gain a good education from "walking the walk, talking the talk" Ha! They both often bring up fun travel memories and are so appreciative of all the places they saw. In school, kids and grands could discuss places they were studying as they'd been there.
Good luck to you. Thanks for joining our Forum, so happy to have you with us!!
Happy Planning!! :)
