Knock'em Hill certainly sounds like the place. In my opinion, this is not worth a drive from anywhere - maybe if you just happened to be driving by. Al reported
from our Glee Club meeting last year that the place is just ordinary. They have a great and enthusiastic ownership, but the food is not up to even middling standards of southern barbecue. This was a case where more is not necessarily more.
So, to the original post....yes, one might find the "largest" smoked pork chop here, I wouldn't call it the best. as I have found better in Texas BBQ parlors.
