Create a toy bag for the parks with sand! Last year I went on a search for a plastic bag/basket like I had when I was a kid… I had no luck after 10 stores. The boys’ mom picked up this mesh laundry bag with a pull-string close, and it has worked out just great! Most important feature – the majority of the sand stays at the park and not in my car! Bring enough toys to share and you have an instant play date.
