Wow, I was excited when I found out about surfboards.com.  I just met up with the Owner of Kahuna Creations a few weeks ago, and I was able to check out a new product that his company was able to innovate, its called the Kahuna Big Stick.  The kahuna big stick is pretty much like a longboard paddle, but for the street.  As you can see from my pictures you use it the same way and you can now cross train when you are nowhere near the beach!
