I don't think of myself as an adrenelin junkie... but rather as a person who wants to LIVE life, not just watch it on TV or read about it in a book. And yet... I have mountain scrabbled... hiked in the Grand Canyon, the Sonoran Desert, a bit on the Appalachian trail and more... owned a race car (and driven it in rally events - lost, but who cares!)... I've scuba dived... lived on a sailboat in the Bahamas... tandem skydived a few times (I have a powerful need to get my AFF as soon as I am able)... I'm a road cyclist who thinks nothing of hopping on the bike for 40 miles of Wheeeee!!!! - though I have no hill skills yet.
One thing that is absolutely critical though... is honesty. I am honest as the day is long and can be blunt as a shovel (though NEVER to hurt another). All I ask for is the same in return.
