Ok so am heading to Plymouth this weekend and am curious if there are any stores orbfrag place but that way. I will be looking to stop somewhere out there Sunday. Let me know.
Where are you traveling from? If your coming from Boston area, the only place that I know of south is Lovely Pets in Quincy and the string of Petco's. If you go southeast, there's Underwater World in Taunton at the Silver City Galleria. Other than that, I'm not aware of any LFS in the area.
Slim pickings in the south shore, that's for sure. It would be worth your time to check out acro garden if you can plot your route that way. Nothing is close to each other unfortunately. The options are very spread out.
