Well... It happened to me yesterday at Wisp (west Maryland). :(
It was green trail and short and wide for in-between trees on side. On the top, I waited to front skier to go away and then wend down. I was the first one (good 150 feet no one was in front of me..)
I took it slow and did little push-pull carving for first few turns and took a little sharp heel-side turn. But a skier was just trying to pass me from behind left. It was a light hit. So after collision, we were going about 10 feet straight down as we stuck together fighting to gain balance back. As soon as I got my sense of control back, I did lean hard for a toe-side turn to escape and give him some room to regain his balance (he didn't and fell down)
Then.... immediate .2 second, I saw a little girl coming straight down and she was just a foot from my right side of my face. The nose of my 4wd hit her left boot so hard her both skies snapped out and she wend down hard. I did front-flip and landed on my chest.
I was o.k. and dragged me down to see if the little girl is ok. It was a quite hard hit. I found out the skier that colide first was the little girl's dad. She cried and moaned. I and her dad asked and checked her if she is alright. What an scary moment it was.. :( She was OK.
At the time when she stood up, whole her family was gathered. They were surprised and overwhelmed by the accident but didn't say a word to me. I was pissed but more concerned about the little girl. Her dad seemed know skier's code well. He didn't say a word except checking her daughter and told her to 'suck it up, stand up, and let's go down hill' to the crying little girl. Then slide down to the base with them. I followed and checked on the little girl again and went my way. Then took a lift to slopes that take me to the base and came home.
I do look up right before I do my toe-side turn most of times. but yesterday, I couldn't. Just plain feel bad and didn't want to continue ride any more.
