The campfire is a-cracklin' on the top of Art Hill right now, and according to the three lone sledders during the morning rush hour, the snow is fine, powdery and dry. That means:
Snowboards and boogie boards: FLYING! (Daily RFT was offered a test ride, and, holy shit). (Daily RFT was also offered a swig of Grand Marnier, but had to decline at 8:33 am).
Plastic shells/toboggans: FAST!
Innertubes: SOMEWHAT SLOW. Although, the snow is getting kind of melty and the main sledding tracks well worn, meaning that tubes will start picking up speed as the morning progresses.
