Cecil,
Glad you're ok. You have taken the first step to becoming an "operator". I know the nauseated feeling that you had, have had it a couple times myself. Like the time I almost drove my excavator under the power lines with the boom up. Or the time I accidentally engaged the dozer while standing on the track (can you say treadmill?). Haven't repeated either mistake, but I wonder what's next.
Don't stop now, a few more close calls and you'll really be dangerous.
