Yesterday I stopped for a $2 pork taco at this little stand on Route 277 near Stephens City, just west of where routes 522 and 340 split at Dinosaur Land. open-faced tasty "barbacoa" on a small double tortilla w/cilantro, raw radish and sauteed scallion on the side. ask for it picante and you get a small container of excellent firey green sauce. $2 tacos, $5 sandwiches or "tortas".
Nice to see a taco truck out in the country.
