i love the EUROTRAX advertisement at the top of the page. all this part and piecing together of nonrelated items (fenders, pvc, abs, bungee, beer) makes me laugh. it reminds me of that tv show JUNK WARS but with junk you have to buy! i saw on the boaters world page fenders for $10. so i quess 4 fenders, 2 lengths of pipe and bungee to make 2 q-tip (registered trade mark) rollers will be around $60.
