Coming from Charlotte Hall, I go up Rt. 5 all the way to Siutland Parkway, then I go thrrough to South Capital St. right past Nats Park and then get on 695 south to Maine Ave exit. Follow that road its either Maine Ave or Independence around Tidal basin go around behind Lincoln Mem. stayinh in right lane then take E st. exit then go about half mile and exit Whitehurst Fwy around to the stoplight make left staying right lane and the merge onto Foxhall Rd. to Reservoir Rd. then amke right. Gurps map is right on it. At end of Suitland Pkwy you can either make a right at the light and go get on 695 or stay straight across the bridge past ballpark and then get on 695 south. Thats the only difference between his way aand my way. His way you probably miss about 5 stoplights. Usually about 1 hr from county line at St. Marys and Charles to the hospital.
