Robertson's Beef Jerky has to be the best beef jerky I've ever had. They sell it at a convience store up the street. I tried it and got hooked. Now I order it by the 1.5 pound jar online directly from them.
Those Luv gas stations carry the 1 pound jars of it also. Its about 19 to 21 dollars / pound, depending on if you order it or get it at Luvs.
