Totally agree on finally learning how to score a game...learned that "on the job" playing softball in college lol. Baseball cards are also another great gateway into the sport for kids (was for me...still have them all from my youth, majority being arranged by my favorite teams the A's and the Tigers). Having the opportunity to see just a few MLB stadiums over the years has been great fun as well as memories...hope to pass those down to my young boy.
I also still have my card collection, which I started decades ago as kid! Those were the days when the Topps packs still included a stick of gum that left a chalky residue on at least one of the cards.
