A few weeks ago, I blogged about plastic rubbish on the beach. But that isn't the only rubbish. A big rash of ugly and largely unnecessary signage is - to my eyes - just as obtrusive and out of place.

These horrible railings and signs were put on the end of the Cobb wall in Lyme Regis some years ago now, transforming a historical monument into a monument to the litigation society. Some idiot fell off the Cobb during a storm and sued the town council for damages. Fortunately he lost on appeal, but this is his legacy.

A few hundred yards west, there is a natural beach, whose wilderness is spoiled by this large and ugly sign, telling us to beware of, amongst other things, tides, rocks, waves and currents. How unexpected on a beach.

On the front proper, there are warning signs every few hundred yards like this. Caution: The shingle beach shelves steeply - as a cursory inspection will confirm.
Stuff like this negates Darwinian selection. The human race will become more stupid and unable to take responsibility with every generation.

As you say, there is a massive creep of signage of all types now, including the defensive type you depict here in your blog. The cost is another issue.
