It looks like [b]"Sea Quest Littleton"[/b] or the [b]"Denver Zoo"[/b] would be the locations of the closest labs. Either way, the starter Pokemon there would be: Snivy, Tepig, or Popplio

And Pokemon in the greater area would include: Sudowoodo, Tropius, Jigglypuff, Diglett, Tauros, Misdreavus, Dunsparce, Shinx, Patrat, Sandile, Tirtouga, Bouffalant, Rufflet, Hawlucha
