Ours still vacation with us. We can't even sneak out of town without them finding us now that we carry cell phones.
In January the daughter (age 21) planned a trip for me & her to Seattle for the 3-day weekend of MLK. We lucked out with awesome weather up there, while it rained here in sunny California.
Hubby and I took the Montana out to the beach on our 3-day President's Day weekend a week ago and the kids showed up later that night with our son's (son is 23) girlfriend in tow.
I have a 3-day weekend coming up near the end of March and our daughter is already planning a "road trip" with me. It could involve taking the Montana, driving the car, riding a train or flying somewhere.
I chock it up to being "neat and groovy" [s]open wallets[/s] parents.
You should too.
