Doing course maintenance and got P'd off with all the weeds, started yanking them up by the arm full and noticed they were floating, Duh. Thought this can't be good, but since no one was skiing that day, it'd be ok. Wrong, a buddy showed up later... i forgot about the weeds and excited to try new fin setup. Just free skiing and turned just past 3, BAM!!! down just as I was reaching Get back up, start skiing again and BAM!!! down again, turns out in the same spot. Bruised ribs, sprained ankle and a mild concussion. Lesson learned, if you're going to pull weeds, put em on shore, on the platform or make sure you don't ski until the next day.
