alright so here's what happend. I was up snowboarding for weekend and i was on about my 7th run. i was almost to the bottom and i was headed to the lift when my foot came off the board, bindings and all. turns out it was just that the screws had become loose over time. i was just wondering if this has happend to anyone else.
1. Check your screws once in a while.
2. Loctite them. Even old and dried out threadlocker is better than nothing.
