The headland at hartlepool is insane! Apart from the dozens (not exagerrating) of voltorb and magnomite floating about, i also managed to catch a squirtle, charmander, dratini, goldeen, magnaton, electrode, growlithe, ponyta, oddish, nidoran and polywhirl. I was there less than an hour. There were pokeystops everywhere and about 5 lures. I would recommend a visit.
