I am in two minds with this. I have to be honest and say that I rarely look at descriptions on the cache page. The GCW series for example I shall look at No. 1 to get parking co-ords, the other 129 I shall never probably look at.
I am sure that some people enjoy reading a good historic background to the cache or the immediate area, but I am not one of those people.
I can't imagine that this particular cache will be up there with the more memorable caches so I can't really see what a description would add to the cache.
BUT, that is merely my opinion
