not a trail sign per-se, but a model of a couple of features that seem to "legitimize" trail closures...
these are borrowed from
fountainhead regional park outside of fairfax VA...superb trail system
* an "official" looking facebook (or similar) page that posts regular updates on trail conditions, and closures. such that, when any asshat is asking if a particular place is open, another asshat can just send them that link. fountainhead's facebook page contact us actually takes you to northern VA park service...would be nice if
this page would have the same info on trail closures...
* a phone number one can call for updated trail conditions (not everyone is on facebook)
i've got a buddy who is involved with NJ state parks pretty regularly. i will ask him for some input here as well. he actually did the GPS walking that generated
this map!
