am doing some research for my sister-in-law. they live by he beach but it is a pebblu type beach. They are expecting end of nov. Am trying ti find them the best puschchair to meet their needs. It needs to be able to go on thr pebbly beach, cope with normal pavement use, go over grassy areas, fit into a smallish boot, be fairly compact as their place is tiny! And be fairly cheap! Is their such thing!
