Mike Fisher is on an unscheduled break from work since the NHL is currently on a lockout, so he and Carrie Underwood decided to head to Idaho for a little death-defying fun. 

Carrie and Mike both posted pictures to their Twitter accounts showing them in various stages of ziplining somewhere in the Gem State. 

In the picture above, Mike Fisher says: @mikefisher1212: Great afternoon zip lining in Idaho with@carrieunderwood pic.twitter.com/oUtOGMe1” Good times!

There are several places to go ziplining in Idaho, including one in Idaho Falls, one in Horseshoe Bend, and one at Tamarack in Donnelly, with others probably scattered throughout the state, but there's no mention of which Carrie and Mike might have visited. Looking at the terrain, the helmet color, and the harnesses, though, I'd say it's Zip Idaho (video here). 

UPDATE:  I just spoke with Eric from Zip Idaho who confirmed that the fun did take place in Horseshoe Bend at their ziplining facility. He says Carrie's people called ahead of time and asked for a private tour, booking the minimum 10 spots for their party of 6.  They then showed up to enjoy some of the Idaho scenery.  Carrie had apparently just had a concert in Portland and was on her way to Salt Lake City to perform on Wednesday when they made the stop in the Idaho hills on Monday.  

So cool this all happened within about 40 miles of my house.
