I have done the ride several times. I lived in NoVA for 16 years before moving to Alabama. The last time I rode up from here I arrived at the North Pentagon Parking Lot at 0630. They have specific guidelines about parking.......... just go where they tell you. We were in the 25th row that early in the morning. When it was all said and done there were 1.2 million scoots there.
It is hot so bring some water if you can, but the do have some there at the vendor stalls. Take something to mark your ride...........aka a yellow or orange rag that you can tape to a windscreen or mirror so that you can find your ride easily. Nothing worse than trying to find your black RG in a sea of black bikes.
If can find one, pick up a cheap folding camp chair and umbrella. Use it while you are there and then once you take off and go past the POW Cage, you can just dump it off on the side of the with the rest of them. Yea it might cost you a couple of bucks, but if you are going to spend several hours in the sun it is well worth it.
The ride through DC is good. The only issue is that a lot of riders take their helmets off to ride the route and then have to stop before they cross the bridge into VA to put them on............. can get sort of backed up.
It is a good ride and good event.............. and the last one.
