I first found out about Pokemon while at a summer day camp. A lot of the other campers spent their time trading Pokemon cards. I hadn't had much luck making friends up to that point, and figured that getting some Pokemon cards to trade would help, so I told my mom about it, and she bought me the Starter Set.
Ultimately, I didn't end up trading those cards (as I wanted a deck for the TCG), but I started collecting other cards I could trade. Later that summer, I saved up for Red Version and started watching the TV show. Compared with a lot of people I knew, I got into Pokemon relatively late (I think the TV show had been on since the previous fall), but I've been hooked ever since.
