As long as he doesn't drop his missus off to walk penyfan on the way he will be fine.
On the subject of penyfan.. I wish people would stop seeing it as some sort of Everest. My niece walked the popular route (the easy one the social media whores use) up and down and didn't break a sweat or complain to stop once. So why do so many lazy ****ers use it as some kind of trophy?
