A little light streaking through the sky

I enjoy trying to photograph the fastest streaks of light that I can see. Of course taking pictures of lightning is fun but my reflexes are not nearly fast enough to just click the camera and catch each strike, so I just point the camera where I hope the next strike will take place and then hold the shutter open for thirty seconds unless one strikes first. The night all of these were taken I was lucky.  (Note: Some of these may have been posted before.)
