Since you're clearly situated on top of a Zubat nest, here are some other nest locations in the Bay Area that spawn Pokemon other than the winged plague of the night ;)




Escape the garbagemon by heading to any of the piers! Lots of fun ones (dratini, dragonair, squirtle, poliwag) wandering in those parts.
Thank you Mr Woodhouse.
I still haven't figured out how to reliably catch Zubats with a Pokeball.
Zubats are the worst! I've hit lvl 12 on almost nothing but them...
If it only cost 25 candies to evolve them, like their earth-bound counterparts, Rattatas, I wouldn't mind how many of them show up everywhere because they'd make for great evolution spam XP fodder with Lucky Eggs.
At 50 candies, however, they're just awful.
100% agreed! Weedles the best :) Cost 12 candies! Easy leveling :)
Where I am, Weedles and Pidgeys are the two best 'Mons to use for power leveling via Lucky Egg evolution spam.
