Interesting sign

Yesterday, as we drove into one of our prime fishing spots along the Ellis River in New Hampshire I felt a little disappointed when I spied this new sign.  On other hand, I found some comfort in it.  The property had always been labeled "private property" though I knew fishing was allowed.  Nevertheless, until I saw this sign yesterday I had always felt a little uneasy fishing there... even though "private property" does not necessarily man "no trespassing"...
