Walking with kids

[Docs Wife]

We are currently with out a vehicle we have 3 LO that I need to get around with (4, 3, 15 mon). We have a grocery store that is appx a 2 mile walk each way. We have a double stroller, with a board for the oldest to ride on, so the distance is not an issue, but there are several areas along the way that do not have sidewalks. We thought a double jogging stroller might handle the dirt/grass paths better but we can't seem to find a reasonably priced one that we are sure a board will fit on. I also thought about wearing the baby and putting the older two in the double jogger but it has been too hot here to wear him while outside for that amount of time while walking that far. Does any one have any suggestions on strollers that might work or any other ideas for getting them around in areas where there are no sidewalks.
