I’d planned to climb Pen y Fan on Sunday, taking the 11 a.m. bus from Brecon to Storey Arms trailhead, but there was an icon of lightning in the weather prediction, so I did not go, even though some people told me, “It probably won’t be a problem.”
About noon, 4 people were injured by lightning and 2 died, right when I would have been up there.
