Hey man, im dedicating my 1000th post to help you out! Don't ski sunnyside or albion lol, they are crowded with ski school classes and beginner runs.
Collins or Supreme are my favorite lifts. Collins has some super fast groomers for warming up in the morning but you can also traverse from the top to a ton of great terrain.
Dont miss out on Catherines, Devils Castle, and if you want to (or if its open) baldy chutes.
Also on a pow day Wildcat is super fun because everyone crowds the collins lift while wildcat has a ton of fun terrain when its deep. Have fun!
