Bweger, I know how you feel.
The last time I went to Canada hunting black bear, I had a wolf come into my bait. It was not wolf season, so I was going to video the wolf. I hit the record button and thought I was recording the whole time. After I got back to the cabin, I went to watch the tape, and found nothing on it. I had hit a button that would require you to hold down the record button to video. Man, was I mad at myself.
