I went anyways. It was misty/foggy the entire time and my car was covered in tiny droplets and light drizzle by the time I got there (definitely more wet in Fairfax than in Alexandria). There were only 10 cars there initially, mostly Challengers and such, but that eventually went up to about 30 cars ~ a lot more BMWs and Corvettes showed up. There were two S2000s, two GT-Rs, and a rat rod that apparently usually shows up at Katie's only. The NSX drew a near constant stream of onlookers, so that was pretty cool. Most suggested I go to Katie's some time because 'there are more cars like yours up there' although at least one guy pointed out that usually there is a red NSX and and sometimes an orange NSX that come out to Fair Lakes, at least when it's sunny.
