Great idea--thanks for collecting.
In addition to the obvious
Prospect Park runs, two good cruiser hills in Brooklyn:
--
Third St. between Smith St. and the Gowanus Canal: two long blocks of wide, well-paved, not-too-busy hill with a four-way stop in the middle (so you don't have to) and a long, flat runout to a drawbridge. Perfect late-night carving. Right near the Carroll Street stop on the F.
Careful at the bottom!
--
Ninth St. between Prospect Park West and Fourth Avenue. Huge, wide, mostly newly-paved street with bike lanes, moderately steep in spots. Traffic and cross-traffic, so best early or late.
Also, any Brooklyn types skate McDonald Ave. by the cemetary between 20th St. and Fort Hamilton? Only driven by but it seems very promising.
