School's out and summer is in. But just because class is no longer in session that doesn't mean you can't continue learning. Make the most of your summer vacation by taking on a cool and refreshing activity. If you're looking for adventure, Performance Video titles on surfing and kayaking will start you off on the right track. If you'd rather enjoy the water without being submerged in it, Scott Baker will show you how to tie practical knots if you ever find yourself sailing the seven seas. Whatever your aquatic pleasure may be, How2Video is a great place to start learning about it.
