Last night provided us with 2 types of lightning, sheet & forked yet strangely, no thunder or rain. Must have lasted for at least 2 hours. Experienced this a good few years ago, pursuing the nightime silver tourists. Before the light show nothing at all happening, during the show, my mate & myself were some 20+ yards away from our rods lying flat on our backs on the river bank. Once the lightning had passed we had some spectacular sport.
