LAKE HARMONY, Pa. (CBS) --  Many people have been happy with the warm winter we've had so far.

But the milder weather is taking a toll on ski resorts in the Poconos.

It's a far cry from last year's snowy season.

This winter- many resorts are closed.

But at Jack Frost Ski Resort- they managed to open one trail to skiers and snowboarders.

Webcams at Blue Mountain, Camelback, Spring Mountain and Shawnee all show snowless slopes.

Some are reporting they've lost 20% of business so far.

But there is some good news... the colder temperatures are back and resorts are hoping to make up for the slow start to the season.
