Just got back from mammoth with a few buddies and headed down to San Diego for some carne asada fries. I swear that is the best thing i've had after a long drive. One of my buddies told me about this site that lists all the taco shops in san diego. Genius! MyBertos - San Diego Taco Shop Finder - Zip Code . I tried searching for any thing in mammoth but it looks like it only focuses on san diego.
