Ever watched a BASE jumper leap off a cliff and start flying? Sunday evening (8pm EST), the National Geographic channel is showing a piece about Dean Potter. To quote part of the blurb about the show: "He can climb the unclimbable, visualize the invisible and fly through the air with the greatest of speed. As perhaps one of the worlds best BASE jumpers, he set the record for the longest flight in a wing suit. Now, Dean has set his sights on Mount Bute - a 9,000-foot granite launch pad along the British Columbia coastline."

Vail's first Winter Teva Mountain Games start this weekend.  Even if you're not an extreme athlete, there's an event for you - the Seven Wonders of Vail.  This Colorado Mountain town is an adventurer's paradise, summer or winter.

Wish I had been wearing CrashPads shorts under my pants when I slid into a pile of rocks and did a number on my leg while mountain biking in Scotland.  This protective sports apparel comes in garments designed to help protect bodies playing specific sports, from skiing and snowboarding to mountain biking, soccer and horseback riding.  You can buy off-the-rack choices or have custom garments made at CrashPads.
