Again, I'm out of Pokeballs in Go (this is becoming a pretty big pain in the butt when it comes to me and this game). One darn CP 112 Pidgey ended up forcing to burn through like a dozen of them before I gave up and figured it was definitely not worth it. Once that happens, the only thing you can really do is just walk to hatch eggs until you find more.

I just haven't found a truly great park with a ton of Pokestops. The local park I usually go to only has one there. It's great for hatching eggs and I've caught a few good Pokemon there, but that's about it.
