I'm sure some people will tell you other wise but I think Northstar is one of the worse resorts in Tahoe. It's really fucking crowded, takes an hour to get form the village to the top of the mountain. The terrain is total shit. They get the least snowfall compared to any other Tahoe resort. I never see that many freeskiers up there, mainly boarders. The parking is such a pain in the ass. Really you should just drive to Squaw or something. I know your friend is at Northstar, but you will like Squaw SO MUCH BETTER. I love it, I can ski there for two days and get 24 hours in. Ride the mountain during the daytime and park at night. Squaw has excelent jump lines too. I like Squaw's park more than Northstar's. Maybe you'll get it figured out and have fun at Northstar, but all the times I've been there, have sucked. Have fun in America though. Hopefully this helped.
