Chopper is the intermediate run immediately left of the Ripper Chair unload.
This run offers a good cruiser, with steeper pitches at the beginning and end of the run.
The middle of the run is a long straight portion that most people take at speed, and can be difficult to keep speed if there is a lot of fresh snow.
Recent work to the run has made it more fall-line, although the old traverse road to the Back 40 is still obvious and shows up as an extra curve on the are map.
Make sure to check the grooming report if you're looking for corduroy, especially early season this one can still have some powder and/or moguls.
