Chansey
Today, on August 9th, 2017, exactly 13 months after I devoted my life to this game, I caught a wild Chansey, completing my Generation 1, Kanto, North American (plus Mr. Mime) Pokédex.
Despite (according to Google) it being a 20 minute bike ride, and only having 11 minutes left, I biked my ass off and made it in 8. Here, I used a Golden Razzberry, and an Ultraball, and on the first try, "insta-caught" it.
Now, Unown and Heracross remain [I have enough candy, rare candy, and evolutionary items to evolve to Steelix, Scizor, Blissey, and Pupitar (and a lower-evolution of each)] from Generation 2. Time to get hunting!
