Yep. My first trip to the Fort---I think June of '73. That was the first summer for the Fort, right?
Anyway, I remember you could buy different booklets with different combinations of tickets. The *E* ride tickets were the best! Of course, they were used up quickly. My dad kept those booklets, as we had some leftover tickets that we never used. I think they were for some kind of horse-drawn carriage or something like that.
