From Route 113 - turn onto Route 9 heading east (if heading north on Route 113, turn right, if heading south on Route 113, turn left). Follow Route 9 through Georgetown, going half way around the circle and continuing east (follow signs for beaches). Approximately 3 miles east of the circle, look for Passwaters Antiques and the green Fire School sign (it will be on your right next to the Sussex Air Park).
From Lewes - go toward Georgetown on Route 9 West. Look for the Georgetown Truck Bypass, just past Megee's Plumbing. There is also a green sign for the Fire School. Turn left onto the bypass, cross the railroad tracks, and follow this road to the Fire School (it will be on your right next to the Sussex Air Park).
