Our Phoenix Zoo membership has served us well for years, but our visits were becoming less frequent in the past couple of years as the kids grew older. From the exhibits to the splash playground to the carousel, we've been there and done that — a lot. But this year, we decided to take the Phoenix Zoo up on its standing offer to bring our bicycles. (Rollerblades, skateboards and Razor scooters still aren't allowed.) Just like that, the zoo became a fresh experience. Our littlest still can't manage a two-wheeler — she rides along in the bike trailer as the big one zips around on her BMX bike. We fly down the hills and through the covered bridge on the way to the petting zoo, careful not to run over pedestrians, of course. We see more animals in a half-hour than we could have in two hours on foot. And the kids like the cool factor: While almost no one else is riding their own bikes, we often hear the people we pass say something like, "Hey, look at that. Let's bring our bikes next time." Our advice, based on the smiles we've seen: Do it.
