Total Solar Eclipse.
I had to drive around 600 miles to reach Madras Oregon, which was along the path of totality. I found a good position 36 hours in advance. On Eclipse Day, I arranged three cameras on tripods and shot. Various camera gremlins crept into the mix, but the best shot is now on my web site [ http://imagetransactions.zenfolio.com ]. Unfortunately, the return drive home was awful due to heavy traffic. It took me 12 hours just to cover the first 100 miles and another 12 hours to return home.
