To get somewhat of a glimpse on what the 200-acre former State School property is, click on "Lakes Region Facility" under references to see a small photograph with all the old red brick buildings.
The lake at the top of the photo is Lake Opechee and the 200-acre former state school-prison property has no access to it, and not to Lake Winnisquam either.
And, here's a 1:54 youtube showing Ahern State Park featuring a mountain biker shot on Dec 7, 2015.......
https://www.youtube.com/watch?v=dNBN3Vl5f6k .... in this video, Ahern State Park looks fantastic, and three cheers for the NH legislature moving to split it off from the abutting state school-prison property back around 1994 named Governor's State Park and renamed Ahern State Park in 1998 ..... hip hip hurray ...... must have been a Fred Toll legislative local power maneuver .......
