I've had a few but the ones that came straight to mind are:
About 10 years ago I was riding my ottb that I had at the time. We were out on a trail and came to a bridge. It was pretty old and made from old railway sleepers/logs/thingys lol my friend went across first avoiding the couple of missing planks nicely so I followed her route. I got about half way over and it started to creak and one of the planks beneath us made cracking noises. He stopped still and we just stood there waiting. I was too scared to move because I thought we'd fall straight through. And we did!! We came out of it ok though. Lots of scratches, bruises, cuts and splinters for the both of us but we were alive and no broken bones yay
The other one was a few months ago on jarred. It was the first time I had ever taken him away from the property for a ride. We were out in a kind of open area and there was a dam that has quite a deep, muddy slope into it. Jarred was being silly because there were some ducks there :roll: and didnt want to go past the ****. We were riding near the edge of it and he started doing that silly sideways hopping avoiding thing they do. His back end was edging closer and closer to the edge and nothing I could do would get him to move forwards. I was envisioning us sliding backwards down the hill and me coming off and being crushed by him or something lol fortunately though one of his back feet slipped off the edge and spooked him so he lunged forward and we were safe
