I was kayaking the other day and my buddy was
commenting on how we weren't burning any fossil
fuels and that kayaking was very eco friendly.  I
agreed with him and then drove home.  On the drive
home i started thinking about how much oil boating
does use.  
My helmet, life jacket, dry top, skirt, paddle,
kayak, fleece for layering, throw rope, everything
was made from oil!  Is kayaking or rafting truly a
enviromental sport when everything we use is either
made from oil or has to be mined.  Me i will not
lose any sleep over it but it is something to think
about since most human powered sports people
consider themselves eco friendly.
