Because the Ft Myer Street will be closed during the event. so you can take Wilson Blv then turn right on N Lynch Street , there are many condominium there, so you can park on the street, there are plenty of parking spaces . 5min walk to Iwo Jima Memorial.
Heh...this is what I get for having lived here my entire life, but never having crossed the bridge into arlington except to go to national airport or to get onto 395. I didn't even know those condos/spaces were there.
