Is it poaching when you go up the down line?
It is a much nicer line, you don't have to deal with their trenched crap and it works.
We call that move "coyote". Smarter then your average dog.
I always try to ride the same line down as I did going up if I plan on playing on that hill for a little bit longer. I hate to track up powder going down unless it is too steep to slow down without it. Would much rather make those new tracks on the way up.
