One time was due to the failure of my brain. Went to lay down, grabbed the hammock in one hand, the UQ in the other, and proceeded to sit, hit the edge of the hammock and on the ground, I was. Lucky that I wasn't hurt just my pride.

The next and last was on a DIY stand that relys on staked out guy lines to holdup the stand. One of the guys slowly pulled out of the ground during testing. I wasn't dumped, but let down....RR
