I’m running a Twitter Stream centered with a bounding box around San Francisco (to be exact, [lon:122.8 lat:37.45]-[lon:-122, lat:38.1)]
There are lots of tweets showing up in SanFrancisco, and some also from other parts in CA which is to be expected.
However, there are a lot of tweets showing up centered in an island 30 miles off the coast, where nobody lives. Why is this happening? Pic of the locations of tweets on the island - http://imgur.com/nxrC8jW
