DC on Memorial day weekend hosts Rolling Thunder. The City is closed to all vehicles except Motorcycles on Sunday for the Ride To The Wall, The Viet Nam Memorial, to honor and remember our unaccounted for POW's/ MIA's. Its a tradition for close to 30 yrs now. About half a million bikes and riders come from all over the country for this event. It's mostly ignored by the media, along with the Viet Nam Vets, but if your a veteran or Patriot it is a moving and memorable experience as 500,000 bikes with flags and Honor Guards cross the bridge and ride the loop around the Mall. It's the only Welcome Home Viet Nam vets ever got, we give it to each other, in DC, on Memorial day weekend.
