My remaining first generation list is: Venusaur, Blastoise, Farfetchd, Hitmonlee, Kangaskhan, Mr. Mime, Omastar, Kabutops, and Dragonite
Three of those are region specific, and the rest are probably candy-walking grinds.
Currently buddying with Omanyte, but it's too snowy for cycling lately so 5km/candy is brutal slow.
I saw a Hitmonlee on my radar once, but couldn't track it down. It was beyond frustrating.
And Dragonite, well, maybe a migration will bring some Dratini to the prairies some day!
