In most places on the mountain, particularly at Sunshine, you have the option of skiing a bumped up line or a groomed cruiser line. From the top of the Divide chair at Sunshine, for example, the run is about 300 meters wide and they tend to leave the center bumped up and the outsides get groomed every night giving you an approximate 100 meter wide bumped line and two 100 meter wide groomed lines on either side. You can usually find a bump line or groomed line from any point on the mountain.
Here are some mid-April pics I took a couple of seasons ago to show you what conditions to expect (at Sunshine) at that time of year. The first pic is looking up from the Divide chair showing you what I just described. The conditions are better this April than what you see in these pics.
