We had such fun yesterday at John T. Edge's signing for Truck Food: 150 Recipes and Ramblings from America's Best Restuarants on Wheels. After locating the current owner of the hot dog cart that John T. & Andy Harper had built over 10 years ago, a couple of Square Books He-men rolled it to Off Square Books, only to find that it wouldn't fit in the door. Fortunately for us, Mayor Pat Patterson strolled by and gave us his blessing to park in the street.  Andy Harper fired the big dog up and we had tasty dogs with pimento cheese topping and beer to celebrate the release of John T.'s accounting of his latest culinary quest---the best food trucks in the country serving up crawfish pie to falafel to hotdogueros.
