Ok, so I aggressive inline skate. I know most of you probably haven't heard of it and thats alright (i'll post a link of me skating at the bottom). Anyways, I was skating a box that looks a little something like this...

I was coming up the right side of it backwards(or fakie), spinning 270 deg. and landing in a grind on the box. (Black part is the ramp and the grey thing is the box.) Anyways I had been doing things like this all night so it wasn't that big of a deal to me. I tried it, my back foot slipped out of my grind, and I ended up on the ground. At first, I didn't know my arm was broken and I was pretty excited to try again. Then however, I looked down, saw my arm was crooked, held it up in the air towards my brother, and screamed, "Oh my God!"
Now to clear up any questions, no I did not have any bone come through my skin. Also when I say my arm was crooked, I'm talking about my arm looking like the parentheses on the zero button. I do have pictures of it on my brothers phone, however, I can't get the off of there because his plan doesn't include picture messaging.
Thats about all the story I have to tell, if you have any more questions though you can go ahead and ask me.
