Thanks for your story. It was very fun to read!
Trigger - Dean suggesting snowboarding
Purpose - to conquer all sports! (a noble endeavour ;)
Problem - Mastering the snowboard
Quest - How to descend down a hill; used the board to turn slow down, and stop. Sub quest: does the face make for a good brake?
Resolution - the hero makes it down the hill successfully, a little worse for wear (or a lot); skills gained
btw - I've never tired snowboarding but when my brother did, he was so banged up that he said he should have just stayed home and had someone beat him with a stick!
