"Temporary Pro Shop" is descriptive. A name is only a name. "Temporary" should be removed from name.

This is a private drive and not an actual road. It is a dirt road used for a farm

Although not on conservation land , this trail and Old Orchard trail is usable. The trail follows a stone wall, and over the wall are "posted" signs from the property owner, a gun club.

Trail now private from here north.

Observed a "Trail closed" sign for the side trail heading N from the main trail

This trail section is closed for repair/maintenance.
