I was cycling on the prom earlier this morning Bri, and the noise was very noticeable and is definitely coming from the Gwynt-y-Mor Windfarm area, so I reckon they must have hit some harder than usual resistance with their piling operations. The visibility was very good and there was a lot of activity out there, and you could see the floating hotel ship right on the horizon, as well as various cranes, rigs etc.
On another note, I seem to remember a post from you last year about a very interesting evening visiting the Penmaenmawr quarries, and I'm sure I have seen an advert in the NWWN or the Pioneer for the same trip this year but I can't seem to get any info on it. Has anybody else heard anything on the subject?
