Shit happens on the hill. You're right that it was ultimately your fault, but I completely understand your frustration about the situation.
Your post pretty much sums up why I stay off of groomers at all cost. I take groomers to get to the chairs to the places I want to go (blacks, back bowls, etc.) and then take groomers at the end of the day to get back to the bottom of the hill. That's about it.
