Alright, Go onto Interstate 66, keep driving till you get onto I-495, go past Tysons and Vienna. Keep driving till you're in Maryland, then keep going on I-495 don't go onto the split to I-270, keep going until you see signs for Bethesda and Chevy Chase, you'll pass the Washington D.C. temple, take the junction to Connecticut Avenue, into Chevy Chase, take a right into Bethesda, i'll be out behind the Panda Express on the intersection of Jones Bridge Road and East Palmer road. Good luck.
