Been talking with a friend who has been in California for a few month now. Turns out the Pokemon there are the complete opposite of the Pokemon that can be found here. So when he comes back he'll probably have everything he needs.
Still haven't seen Ekans in the wild, lol.
Yep, if I look at fastpokemap in LA I see everything that's very rare here: Ekans, Growlithe, Mankey, Machop, Sandshrew, Geodude, Vulpix, the works.
