So I've been thinking about this a lot, and wanted to know if this is something we can/should actually push for. If there is a chance the quarry is turned into a mtb park of sorts, the surrounding area will undoubtedly become more popular and I feel it would be good to have more access/a better relationship with Washington's crossing moving forward. Given that most of the reviews (both good and bad) for Washington's crossing make mention of poorly maintained trails (overgrowth primarily) I feel it would benefit the park to have a volunteer group that more regularly maintains the trails.
Further, if we are able to connect Baldpate to the Lambertville water company trails (if I remember correctly it is a short stint on a road on the backside of Baldpate to the connecting trails) it could be one of the largest "connected" networks in Central NJ outside of Allaire.
