Got the last two that were on the shelves at Total Wine Fairfax last Friday. (although they may have had more)
The Rustico in Ballston had a keg of it on Saturday - and (given that the PDF was uploaded today) they still do according to the draught list.
Ricks got it's allotment last week and it's already gone. No more left at Hop and Wine. So whatever you see on the shelves is whatever is left.
Not a surprise here, but if you need to go into College Park for some Stone RIS, Village Pump Liquors has a bunch of them as of May 14th
