All winter, skiers sliding down the steep slopes at Ski Anthony Lakes took advantage of gravity.
On Saturday the snowmobilers will defy it.
The annual snowmobile hill climb will start with a mandatory 10 a.m. meeting for all riders at the ski area's lodge.
Helmets also are required.
Riders can compete in any of three classes: stock, limited and modified.
Riders who register before Saturday pay $25 (plus $15 for each additional class entry per race). If you register Saturday you'll pay $40.
To pre-register, call Jerry Krieg at 856-3277, extension 12; or Jason Harmon at 541/663-0567.
Ski Anthony Lakes' lodge will be open Saturday, as will the Starbottle Saloon. A limited menu will be available.
