Climbing mountains, I've been stuck out super exposed under thunder storms a few times. Sitting on glacier, knowing that if the mountain gets struck anywhere, you're going to get zapped to some degree... fortunately, I never have. I know guys who have, though. Near misses hurt, but they don't kill you. If it's not wet/glacier, near misses are usually just that- misses. Scary, but no pain.
Closest strike I've endured was probably a quarter mile... still scary as hell, but might as well be 10 miles away, for all the harm it does you. If you're not a prominent feature in the area, you're not likely to get hit. You just have to resolve yourself to not worry about it. Lord God, if it's my day, please just let it be quick. is a prayer I have prayed many times.
