I just got sent this article about what is happening over in England during this frigid weather winter to keep progressing your wakeboarding. Since its been brought up a fair bit on here over the years, I'd thought I'd share.
Check out all the rigs they have set up. I think it would be a pretty cool thing to do when you cant get on a board over the winter.
