Pokemon GO Bouffalant: How to Catch
Bouffallant is currently only available in and around New York City. Based on personal testing this does include areas of Long Island. This is likely in reference to the fact that areas of the Unova region, such as Castelia City, are based off the New York Metropolitan Area.
It is likely that Bouffalant's range will expand further after Unova week however, if you want one right now you'll have to take a trip out to the east coast.
