I went and talked to the owners of properties at the south end of this trail as mapped. The path does exist. I'm not sure how much I should put in writing here but basically the path exists, it has occasional use by hikers and runners, and no-one seems to have a proplem with it. There's certainly no sign saying "No Trespassers" etc. It seems the path should at least be mapped as access=permission. There is a new house going up soon that might change all this, but given that the trail seems to be right up against the parcel boundary, I doubt that'll change. And anyway we're supposed to be mapping what is there right now, so here I go.
