问题
I was wondering if anyone had any experience with a good plugin/gem that pulls city and state from the IP. I've tried the one built into GeoKit but it's terrible. I don't mind paying for it as well but I would prefer free.

One of the best IP to location products is MaxMind's GeoIP.
The MaxMind GeoIP City does cost (http://www.maxmind.com/app/city), but there is also the MaxMind GeoLite City (http://www.maxmind.com/app/geolitecity) which is free, but a bit less accurate and not as frequently updated.
