Yes, all weakened and then blown over in a recent storm. Corrosion from sea-salt in the air maybe?
There are tens of them about, which does not seem normal
Are you all talking about ice melting/traction increasing salt? That stuff is so gross to me, in my state they said some 60% of waterways and bodies were overly salinated and basically ruined, and that was several years ago with no real sign that it would have slowed down. All because of over salting, or at least mostly because of that.
Wow, that's sad. Yes we are, they really layer on the stuff here, at places where the lorry has to pass multiple times (e.g. a roundabout) you can even get 'salt dune' deposits from it building up.
Wrecks the drivetrain on my bicycle - inevitably have to replace components once winter is over.
