Kept a passenger log - my dad's logbook provided most of my pre-teen info, probably a few gaps tho where he was a passenger too, lost my Junior Jet Club log but I know when, who and what those five flights were, can guess the hours!). Most interesting types, Chippy, Pup, Cv440, Waco UPF-7, Stinson SM-8, Bell 47, DC-3, S-61N, floatplane J-3, Citabria, Rapide. Think there are just over 30 types all told.
