Steuben Park In Clinton Hill Is Now Off-Leash? Since When?

I had my pup down at Steuben Park this morning and I saw the sign that said dogs must be leashed from 9:00AM - 9:00PM. Steuben had always seems to operate as a below the radar, unofficial off-leash park so I was quite surprised to see the sign.

When did this change take place?

I know that the Clinton Hill Dog Run people were trying to turn the park into a 24/7 off-leash park but I didn't realize that a compromise position had been reached.

Most of the big parks adopted a 9 - 9 rule a few years ago.

I suspect that the Parks Dept is just now getting around to putting up signs, and it is unrelated to any advocacy done by the Clinton Hill Dog Run people.
