I was on the train, which probably did pass pretty close to you but didn't really allow for stopping off, and then I was with Marnie, Sue and Carol the rest of the time. Tell you what, I'll come up again sometime and stop in to see you (you'll have to tell me where to get off the train and come meet me there, though) and we'll pop up to Pen Pych and do the waterfall walk together! It is indeed the one that can be seen from the Rhigos road.
