Forget that other link. Just go straight here and check out the maps on the right side. They got the track I was talking about - Pelham Bay Park South.
In the interest of updating a page I have on NYC-area tracks, could people give a blurb on the logistics of those tracks with which you are familiar? Full credit given.

(As an aside, you can get to the OCA in the Bronx from the No. 4 train as well as the No. 1.)
Has anybody used the track at George Washington High School in Washington Heights or the track at City College near 137th Street?
