I was in Jordan doing a jump with a bunch of people I hadn't jumped with before onto a drop zone that was like the surface of the moon, covered in sharp rocks. I let a guy rig my 'chute super tight, which normally is fine, but this time when it opened it pinched one of my boys against my leg. It was so tight that I was trying to climb up the riser the whole ride down. I couldn't get any relief. I was narc'd up and laying on my back for about 5 days. I still have residual pain sometimes (it was in 2006).
The jump was so bad that that the Doc covering the drop zone did about 250-300 stitches on various dudes, and we had to take one guy into Amman to get a CT 'cause he wacked his head so hard when he hit the ground that he had awful whiplash... something you can relate to

Thankfully, the jump was the last of my obligations that trip and I got to go home shortly afterward.
