Directions Corner of Calvin and Holloway Streets in Durham Right across from the Police Substation --- large building with a flag and black iron fence. Our building is a short white building with a small sign over the front door that says "Crayons2Calculators" If volunteers could park on Calvin Street instead of our parking lot, that would eave space for the teachers to park since they carry large bags and boxes to their cars.
