Awesome. Good for you two. Don't know if I'd be able to do that. Did have one of my bosses years ago do the exact same thing. She quit, sold everything and she and her husband bought an RV and traveled the US.
If you make it to the Chicago area, give me a buzz. I can cook you up some que... No wait, I'd probably make YOU cook ME up some que.
Nah, I'd just take you two out for a big ol' Chicago steak dinner.
Best of luck on your new adventures!
