I have never parked there, but I believe some group rides use the school parking lot to access the LLF. From the Estabrook school website:

"Due to summer construction work, the Estabrook School property will be closed to the public effective Wednesday, June 26, 2013. The school, playground and parking lots will not be open to the public. The property re-opening date will be announced late summer. "

I have been told that there is already a fence up at the school.
