Mine disappeared, but a new site that's actually a bit closer just popped up. None of the cars in my part of town are on-street; they're all in paid private lots. Apparently Enterprise won some of the on-street spaces in DDOT's 2011 auction, but they may have subleased some until their recent launch.

BTW, among the paid-lot-parked cars close to me are two at the Hyatt Capitol Hill; took a good 15 minutes of negotiating with the valet staff to get in/out of the garage, including tailgating one to enter. It was a bit nerve-wracking, seeing as we're paying by the minute for the cars.
