Caught: 19 Seen: 22 (Squirtle, Caterpie, Metapod, Weedle, Kakuna, Pidgey, Pidgeotto, Rattata, Raticate, Spearow, Nidoran, Nidoran, Jigglypuff, Oddish, Venonat, Seel, Shellder, Drowzee, Eevee)
The seen ones are Magikarp, it broke out of the Pokeball and fled. And Goldeen and Zubat, both times the ball froze like it does after about every two catches and I had to delete the cache and it erased them but did file them as being seen in the Pokedex.
I had countless Pokémon appear on the nearby thing though, Lapras, Dratini, Electabuzz, Jynx, Tauros, Koffing, Staryu, Pikachu, Charmander, Abra, Golduck. Unfortunately none of them were feasible to actually catch, and even then I doubt a Pokeball would catch them. Either they flee or the ball would freeze like it does 50% of the time.
I think the rarer Pokémon spawn farther from your house, so you have to drive miles and miles from your house to see them. But that's not viable what with gas prices and accessibility. On the brightside I can have a full team of Pidgeot and Raticate.
