Locaetd next to the shop is a lone trailer. This is most likely where the shop owner lives. Usually a Freeway, Sanchez, or Wayfarer will spawn near the the trailer. On the other side of the shop is small path that leads to a pond that puddles up from a small river which is fed by the Sherman River. At the pond there is a small dock that is meant for fishing.
There is nothing to do at this bait shop and the shop itself cannot be entered.
