A little video of canoing the Spring River in Arkansas. Some good examples of how not to do it.
Funny. Youtube has turned into my greatest enabler. All of this stuff I get into, or want to do, and that I wish I'd done 20 years ago, has warnings attached due to the risk involved. Canyons, caves, cliffs, rivers, and now MTB trails with difficulty ratings that I find daunting as a beginner.
I'm a huge believer in training, so I read, gear up, train, practice(yesterday I spent half an hour riding in circles hopping over a log with my bike

), and wonder if whatever it is will finally be the thing I do to get myself killed, because I'm not adequately prepared.
Then I get on Youtube, and find videos of all these morons doing the things I've made myself nervous thinking about. Most of them don't have any common sense, don't have proper equipment, or any competence with the equipment they do have. Suddenly the mystery is gone, and away I go.
When I get my bike out again, I'm going to ride a trail I avoided last week on my first "real" mountain biking experience due to it's "more difficult" warning sign. Because I found a youtube video of it...and realized the ATV trails I've been practicing on are a LOT more dangerous.
I like that converted trailer.
