Heck wander around San Francisco and you're gonna get tons of different ones! In about two weeks I have filled most of my slots, for two separate accounts!
A friend of mine said she had been seeing a lot of nice Pokemon south of the San Fran 49ers stadium. I don't live in California nor have I ever been there but just thought I would share. She is an online friend.
Just an FYI that I found three Jirafarig yesterday in Santa Monico. First day that I have ever seen them there and due to the large number of lures, I don't know if it was due to those or to the area. Also, other pokemon that I found while there were some Qwilfish, one Flaaffy, a Mareep, and a crapton of Sandshrew and Sandslash. I have fully expanded my pokemon bag to 1000 and in two hours (using my PGPlus) caught about sixty of them. If anyone could tell me about some Grimer or Muk, that would be great!
