Heights !!!!
It came upon me suddenly. I had taken the family on vacation to Colorado and we drove to the "Great Gorge" ... a 1200 ft ravine.
At the "Great Gorge", they have a parking area and a loooooong concrete walkway that juts out over the ravine. I figured it would make for a great picture. The wind was blowing real hard so I suggested that the wife and kids stay in the car while I snapped the shot.
I got about 3/4 of the way out onto the walkway when something inside me freaked. I had absolutly no control over what happened next. In the blink of an eyey, my body threw itself to the ground and I found myself frozen in a prone position ... flat out on the concrete.
Took me a good minute at least to regain some control. To try and save face, I then willed myself, crawling on hand and knees ... VERY SLOWLY ... to the end of this walkway. I then grabbed each bar singley and slowly pulled myself up to a poistion so that I could get the shot.
Slowly I lowered myself back down onto my knees and crawled back to a point where my body would allow me to walk upright again. As I approached the car, I could see the whole family was laughing uncontrollably. My wife was laughing so hard she had tears running down her cheeks. 'Twas not a laughing matter to me. They then wanted to drive across to the other side. Yeah right ... a freaking wooded bridge across a 1200 ft ravine ... not gonna happen.
Since that day, if I see a similar type seen on TV or in a movie, the hair on the back of my neck stands straight up and a shiver runs through my nerves.
Never had the problem as a kid ... somewhere along the line, the "mortality" switched had been turned on..
