well, being that a knee injury that ended last season, and this season before it even started, occurred after my cousin called last run, yes I am superstitious about it.
The only time you may call last run is if it is the last day of the season and you're about to be part of a massive train. The awesomeness of the train will appease the snow gods.
i learned a lesson. last sunday i called last run, hit 5 rails, bailed hardcore and hurt myself on each. I could barely stand on my feet at the bottom. never again.
