A couple days ago I was riding pretty well (by my fairly low standards) in the park. By the last run of the day, my confidence was pretty high, and I decided I would try a 270 onto the tiny rail in the start of the park. I've never attempted a 270 onto anything before, and really should have started with the a mellow box, but i was dumb and and confident.
I ended up going fs 270 since i'm more confident with fs 360 and fs boardslides, which in retrospect was probably another mistake, since going backside would have allowed me to spot the rail as i hit it and control my slide without counterrotating my body. Though maybe I'm wrong and fs will end up being easier.
Needless to say (since this is the slam section of the forum) things didn't go well. Ended up falling hard and slamming my arm on the rail just above the elbow.
My whole arm went numb and my first though to myself was, "you idiot, you've just ended your season with a broken arm." Luckily, after a minute or so I could move my arm and feeling came back. Ended up bypassing the rest of the park and calling it a day. I got off pretty lucky, no breaks or fractures. just some nice bruising where the rail hit.
Next time I'm going to try to 270 onto a box instead. Hopefully I'll have better results.
