If you've already conquered the small whitewater rivers near your home and you are setting out on a trip to raft some serious whitewater (class 4, for instance), then you will need to be specially prepared. Many rivers have leisurely runs with small whitewater sections that are not challenging or dangerous. Of course, if you're already run the small rivers with class 1 and 2 rapids, you might be up for something more challenging, not to mention more exciting.
When was the last time you got outside and really enjoyed your time away from work? A few years ago, I realized that there were some real problems with the way I was spending my free time, and it really caused some issues. For example, I was starting to gain an inordinate amount of weight, and I could really feel things starting to slip. I decided that it would be smart to start focusing on recreational activities and sports, and that simple decision saved my life. Within a few short months, I started feeling more energetic than ever before, and it was really powerful. Check out this blog for more information about spending time in recreational settings.
