Wife and I are 63 and now that her knee surgery is over are wanting to plan some vacations. We have been to a few places es, Alaska, Canada, carribean. But what i want to know is for the man and wife your best vacations and why? We want to take a western u.s.a. trip for sure some driveing some flying. Maybe fly into cal and rent a car and drive back. Scottland is on her bucket list so I guess it's on mine too! Trying to get some ideas and see if we can make them happen! We're not getting any younger for sure so the time is now!
