Jack will be 3.5 when his sister arrives, and I want something for trips to the zoo and other local amusement parks, and long walks. He's pretty good on foot, but kids get tired and no one wants to carry a sweaty preschooler around the zoo. It really won't be for every day stroller use, just for the occasional "in case of tired kid" use.
What kind of stroller would you get? And please don't say a BOB/Phil & Ted because I don't want to spend their college funds on a stroller. I found a MacLaren Twin Traveller for $45, but I can't find any new info on that stroller so I don't even know if it was made in the last five years.
