This is not a good idea, and I have seen them check carefully.
When you purchase a pass, you sign an agreement that includes very clear points:
- Your season pass will not be used by anyone but yourself.
- In the event of a transfer to or use by another, the management may revoke your season pass at anytime without a refund.
- Your season pass is the property of Whitetail.
So not only would you get in trouble (and possibly escorted off the premises by the police), but your friend's brother could lose his pass. Because Whitetail is private property, they could further ban you (and the brother) from using their facilities in the future.
The mid-Atlantic ski season is short and it is difficult for local resorts to make money. Whitetail invested nearly $3 million last summer in improvements, and it takes a lot of lift tickets to recoup that kind of investment. I know skiing is expensive, but using someone else's pass is a form of theft. One way you could save money if you go enough is to buy an Advantage Card at Whitetail. It's $119, which is much cheaper than a season pass, and gives you a 40% discount on lift tickets and lessons, and every sixth lift ticket is free. It's not a bad way to go.
I really don't mean to sound like I'm lecturing -- but it's not a good idea to share someone's pass! Hopefully I've talked you out of it.
