This is a concrete surface. The correct type of wheel will depend on the temperature. When it is warmer we typically use a 78-80 hard wheel. In colder weather I drop down to a softer wheelof 76-78.There are no boards but you are able to use the walls as boards for passing. As you can see,the surface is large enough for 5-on-5 play
With the United Nations Building as a great background, they once filmed a scene from "Love with the Proper Stranger" in 1963 staring Steve Mcqueen. Here are some additional old Alumni photos from the 1970's.
