I had planned on the Shore Parkway this past weekend, wish I had done it, as I'm pretty sure it could be treacherous. It's not plowed for traffic, and doesn't seem to get as heavily used as Ocean Pkwy, so the odds that it is clear seem dubious... Also, the area is definitely sketchy for riding at night, I usually try to avoid that down there. Might give it a shot this weekend, it's easier to deal with patchy ice in the daylight.
