Mommy and Daddy can't decide what we want to do today. Haul the jogging stroller to a hiking trail along the Potomac River? Hook up the bicycle trailer and head out on the Washington and Old Dominion trail?

Either way, stuff with wheels will make a good workout in the nice weather possible with our toddler. Some might think it's crazy to have three strollers, as we do. But once your kid weighs more than 30 pounds, putting them in a body carrier just doesn't work. We've put plenty of miles on the jogging stroller, and not all of them jogging. Trekking over grass, mud and stone is nearly impossible without one. Certainly, an urban or suburban walk around town serves as a wonderful workout with a conventional stroller, too. We just love being among more trees, water and wildlife. And the jogging stroller makes it possible.

As for the bicycle trailer, that was last year's Father's Day gift before we spent a family weekend vacation in Chincoteague and rode rented bikes around the nearby Assateague Island. Our daughter loved cruising along, looking out the plastic windows, safe from the mosquitoes that seemed to be hatching faster than you could say no DEET please. The really cool thing is that mosquitoes couldn't make a swift landing on our skin with the breeze whisking past as we peddled.

My point is that stuff with wheels have been a crucial element for our active family activities that have been well worth the investment. You don't need to spend a lot, either. Both the jogging stroller and bicycle trailer were purchased at Target for a little more and a little less than $100, respectively.
