Dave,
you are right re: jetties. if it impedes your path along the shoreline, you can walk over it
(as opposed to wading around etc.). The "walker's welcome" signs are probably posted to prevent
the public from gaining public or prescriptive easements--if the property owner gives explicit
permission, he or she maintians his/her private property rights against the
public in the future, so they don't lose their right to exclude the public
if they so choose. NO matter what, you still have the right to fish fom the shore
below the dry sand area...
Man, things must be pretty bad in your neck of the woods. I grew up fishing off of jetties
and piers down around Chatham and Harwich when I was a little kid, and I don't
ever remeber even seeing a private jettie, let alone get kicked off of property
for fishing...

ps. you run a great website Dave, despite your unique method of "chumming the
water."
