Oh yeah, Sparky's. I went in there, and felt like a Martian. People did not seem to want "an outsider" in their little club.
I worked at Spag's in the early 90's. They sold ammo in the front along with nails and hardware a long time ago. They sold it in the sports shoppe when I was there. I NEVER remember them selling guns. I remember Prime Value Mart in Worcester, over near Union Place, before the Centrum. Of course, in the old days, there were a lot of people who were gun dealers out of their house.
