Replying to Extreme snowmobiling in keystones park

so today im riding up keystones park lift and 2 guys from the park crew are trying to tow a wood wall ride thing up the hill with a snowmobile. there is a guy on the snow mobile and a guy pushind with his hands. the dude on the snowmobile looks like he put the thing in park and while he was about to get off, the snowmobile rockets backwards, because aparently it was in reverse and it runs over the wood thing and hits the guy that was pushing, and ends up upside down. the ood thing got broke too. funny shit.
