I'm at a bench over in Columbus Park just south of the fountain in the middle of it. There are four bicycle parkings a little to my southwest off Worth Street. Go about 7 blocks west and then go south on that road.  You'll pass through Chinatown and the wlan hotel.  You'll also pass a doctor's office and Lin Zexu at the intersection you need to turn right at and go east (Worth Street) You'll see the park and the bicycle parking I mentioned. If you pass the courthouse you've gone too far.
