Here is the latest round of slides that I was able to find and scan in. Some of these are from our Alaska trip in 1964. Captions are included where it makes sense. Email me at [email protected] with questions/comments.

Zion NP (1965)

Zion NP - This is not our trailer. My dad must have waited for an Airstream! (1965)

Yosemite NP - Almost looks like an Airstream promo shot. (1965)

Yosemite NP - The ultimate tailgating! After this, my dad put a table mount on the outside of the trailer. That way we could take the table out of the trailer and attach it to the side and then eat outside.

Not quite sure. Could be Sequoia/Kings Canyon NP.

This shot (and the following ones) are from our 1971 (or 1972) Florida trip. We went to see Disney World which had just opened.
