I got some of the smaller bins with part of the side out that you can stack. I put a few cars in 3-4 of them and then spread them out. First it means no matter where they are - near the table, near the garage, etc. there is a bin of cars to use. It also means when I find one sitting around and pick it up that I am only a few steps away from the nearest bin. We too have cars everywhere. The good news for me is that the older boys are off to school and I am left with two girls and new babies so MOST of the cars will be disappearing in the next couple weeks a few at a time so they aren't suddenly missed. I will be leaving more larger type cars out that all ages can use.
