I think it's the holy grail, personally. Probably because of all the BBQ's and Picnics i've ever been to I've never seen it served (apparently I'm the only one in my extended-extended-family with a smoker). I've seen the usual hot dogs, burgers, chicken, ribs and even pulled pork but never brisket. So, to me, it's the holy grail because the only time I ever get to eat it is when I cook it myself, which I plan to do quite often now that I have a better job and a pit of my own.
