You NEED this Thule cargo carrier for when you're on those long strolls with the baby. The extra cargo storage above your stroller is a MUST - what else are you going to do with all your neat rocks and gems? You're going to be the talk of the town when people see you stroll by in style rocking this cargo carrier on your stroller. OK - full disclosure I don't know anything about babies, strollers, or cargo carriers. I got this given to me by a friend - he said it was worth $90 which I confirmed on Amazon. No idea why he thought to give it to me - I don't even have a girlfriend, let alone a baby :(. $30 OBO
