I grew up a few miles from here and my grandma lived nearby (in fact, I can see where her house was near the Causeway). It’s BS if Gulf Blvd doesn’t count!!
I think it’s because GB, because of OSM, "belongs " to to the city on the other side, east of GB. Perhaps Belleair Beach. I’ll be hitting it next. This was just a quick trip up from St. Pete Beach.
