Since this is a private path, biking is not allowed. But push! The last approx. 500m are difficult to recognize as a path. I wouldn't drive here much longer. A local resident even unfriendly blocked our way. A pity!
@Wanderer: The way I read it, you're one of the property owners! A trespass suit requires the owner to know your identity? How would he know? Therefore, he can't sue you! Friends, don't let anyone spoil your fun...
