Other peoples' areas are different than mine, I see. I haven't seen a single Pinsir or Growlithe or Vulpix or Doduo. I have Eevee and Clefairy and Drowzee for days, though. I caught, like, 5 Drowzee in a row last night and evolved my second Eevee.
Also saw ANOTHER Squirtle last night, but this one fled from me, dammit.
Did catch a Jynx, though.
