I agree OregonMouse. With lightning if you have to move, then move. Don't ignore it but don't worry about it. But one of my favorite bpking trips with my kids involved an intense 3 hour lightning and hail storm near Waugh Lake in the Sierra Nevada Mountains. All 4 of us hunkered down in our tent and played indian poker the whole time. I don't think the four of us have laughed so hard, with occasional screams with the really close ones. Then again, no one's hair was standing up on end either and I was confident of our campsites location.
