Choosing Locations - Back Garden

For the second part of my film opening, I need to create a long line of rubble and debris that I can motion track credits on to. My Grandmother's back garden has a lot of bricks and concrete slabs that are piled up ready to be disposed of. There is also a lot of gravel. I have asked if I may use these things to create the look of a line of parts blown off of buildings, et cetera. To make things more convenient, there is a driveway at the back of the garden and a gate which leads out on to a road behind the house. This concrete driveway is relatively smooth, which might allow me to use something like a skateboard as a dolly for the camera as I pan along the line of rubble.
