Daddy could do a wicked ollie in his day. So it’s no surprise that you’ve got a pint-size thrasher on your hands. Surprise him with a locally made skateboard bench by Grind and Unwind. The durable creations are fitted with iron pipes for an industrial look and are sturdy enough to double as step stools. Go the ready-made route or have yours customized with a choice of graphics and colors. Pops can even donate his old deck and a craftsman will make it into a family heirloom that’s truly cool. Which is quite a trick. Available at Mew Gallery, 906 Christian Street (215-625-2424 or mewgallery.org); custom orders available by e-mail (firstname.lastname@example.org).
