These directions assume that you will be approaching Media from the "Blue Route," Rte 476.  Get off Rte 476 at the Swarthmore-Media exit, #3.  Signs may also say Baltimore Pike, Springfield.  Head west toward Media.  Move into the left lane after you pass the first light and stay there.  The third light is at Rte 252.  At that light the right lane has to turn right, there is also a left turn lane.  You will be in the middle lane which is where you must be to go straight forward, continuing on Baltimore Pike.  Go past Rte 252.  At the fifth light beyond Rte 252 (about 1.5 miles from Rte 476), turn right on S. Olive St.  Cross State Street at the light, then make your next left (after 1/2 block) onto West Jasper.  The first building (actually the rear of a building) on your right will be 103, we are the second at 105 (in large letters on the building).
