I got my 1st concusion riding snowmobile. Was just a young and dumb mistake. I was haluing ass accross a open field in some new fresh powder probably going around 80mph (Since it was new snow, it felt like I was floating), I came up to the edge of the field and it wouldnt break quick enough. At the edge of the field with was a very deep plowed field. I hung on as long as I could but it was wayyy to bumpy and threw me around to much and ended up dumping me off, and the sled ended on its side. I laid there for what must have been a good 15 minutes before I could finally get up and ride home. Luckily I was wearing a helmet or I would have been worse. I had to drive about 3 miles, and went in the house, laid on the couch and was in a daze. My parents ended up bringing me in because my pupils were really big I guess. I just had to take it easy for a couple days, and went back to snowmobiling.
