Don't know if it's common practice but farmer on Brecon to Builth Wells Road spray painted his sheep fluro pink this year. Not sure if it was to improve visibility or to put the locals off I'm not sure...
Saw this yesterday, I do wonder what the financial impact may be on the Ponderosa as I am sure it may put some bikers off. I tend to ride from the Ruthin direction rather than the Llangollen direction to get to the Ponderosa so not much of an impact as it's only a short section of the pass that way, the Llangollen way is far more interesting and mostly good visibility so not sure why TBH.
