91. Kayaking If you are a little adventurous， like water sports， and enjoy being around nature， then kayaking is definitely for you. Floating， drifting and speeding down rivers is all part of kayaking. What better way is there to spend a boiling hot summer day？ And if you think it is dangerous， you re dead wrong. It s so safe， you don t even need to know how to swim！ Everyone wears a life jacket while kayaking. So， you see， it s not a sport for the brave only. Kayaking may look difficult but it s really very easy. Sea kayaking can be learned in 5 minutes！ However， it takes about two days to learn river kayaking. And for an estimated US$1，500， you ll be able to own all the proper equipment， including the kayak. It s not cheap， but good things seldom are.
