I too have a lot of cookbooks, the General ones (Betty Crocker,Better homes and Garden) etc. are from my parents and are Circa 1960.
I have a ton of Grilling/Barbeque books, seems like for awhile every Xmas and Birthday got a new grilling cookbook.
I dont really use them for recipes per say but more to get ideas and tips.
Thay said, I find myself looking on he web more and more when it comes to ideas.
