In honor of 4th of July festivities which are quickly approaching, we set out to get the scoop behind two of the people serving up an All American classic to the people of Cornelius, hot dog vendors Mary of Zima’s Steamin’ Dogs and Brandon of B’s Grill! Taking turns occupying Catawba Avenue, you can be sure to find a hot dog cart in the heart of Old Town Cornelius at any time of the week from Zima’s Steamin’ Dogs or B’s Grill.
