Are you looking for a little adventure in
your life? Travel with me to beautiful
Colorado. I’m an experienced river rafting
and rock climbing guide. I’ve been guiding
adventure travelers in this area for 10
years. In fact, last year, I took 30 trips
down the Colorado River. Oh, and don’t
worry about safety. I’ve also taken a
number of first aid and safety courses. No
one has ever broken any bones on my
trips!
