Death by Riding Mower?

Over the weekend I drove a 54" riding mower up onto the ramps carefully placed onto the tailgate of my GMC pickup truck. The deck of the mower snagged the lip of the tailgate. No big deal; back it down and start again. On the way down the deck caught a portion of the right ramp and within a blink the mower, with me in the saddle, is crashing to the ground and threatening to roll over. Not a good thing. I could see the next morning headline, "Murray Mower Kills Man in Alabama."

Life suddenly changes when, the things you are counting on for support, give way and come crashing down. Kinda like the stock market or job security or, well, you fill in the blank.
Fortunately, the mower did not roll over cause I'm not sure I could have dismounted in time to same myself some major embarrassment and long term pain.

This incident has got me thinking about other things I place a lot of trust in and how secure they might be.

Ever had an similar incident that has stirred you to reflect on the dependability of your "ramps?"
