The U.S. Forest Ranger told you the samething that Brad C. Burns told me 11 years ago. The rule is: "You must be dressed anytime you are within one quarter of a mile or less from any public roadways, towns and etc..... or run the risk of being cited."
That one quarter mile rule probably applies along the public open routes of JF3, 4 & etc... as well as 3n59A and all the rest of them as well.
