Hey wanna keep your grinding skills up in the summer without buying skates or soaps or going to summer camp? Cut a old skateboard deck in half and duct-tape old shoes to them. Find anything plastic and flat to duct-tape to the bottom of the deck. Now you have an awesome pair of new grinding summer skis. Find a rail and atach it to your tramp going down. It takes 10 minutes to get used to but then it is soo awesome.
