I recently bought a passport book for myself, but wanted to revisit parks previously visited to stamp and get stickers.
My Mom, however is older and has visited so very many of the Parks - and isn't likely to revisit - but this is a great way for her to revisit those memories. I know she has been to Grand Teton twice, but the first time was on a family trip - she was SO EXCITED to see the Rockies, and for her this Park was one of the highlights. GREAT MEMORIES...
