scarce or nothing.
That's where I've gotten most of my low carb recipes. I learn mega stuff about the latest medical trends/theories and nutrition. How to restore cast iron pans. And how to care for and propogate aloe vera and Thanksgiving cactus. How to make organic fertilizer. Even one or two that helped me fix a couple of problems with my old Bernina machine that had some issues with locked up parts. More things than I can even remember.
There IS a lot of crap to wade through sometimes, but when you find the jewels you're looking for, they're worth keeping. I'd hate to know one of my most valuable resources was gone.
