I did a bunch of laps with some people from fixed gear forums, the park is absolutely clear but some spots are moist and there's a tiny puddle at the downhill plus a police horse was spreading manuere.
The streets are pretty clear but some home owners are starting to throw ice onto the street from the sidewalk for it to melt. The pulaski bridge (for the very few people who go that way) is completely covered in ice so take green point to get across.
