I think I may have found something. I've been looking or a container, something small, clear, and with a lid, that we could leave at Andrews spot. Something that we could put things in that we want to keep dry from the rain. It's okay if something gets wet, but a lid to at least hold most of the rain away. I've looked at Michaels and online and couldn't seem to find the right container. Then, it came to me. So simple. The little clear containers at the Container Store. I plan on heading there and trying out a few different sizes. One that could fit a little race car would be great.
I share this for mothers out there who might be in the same situation. I'll let you know how it works out.
