Nature is a source of strength.
There's a great post about how to spot nature in urban areas with kids over at the Go Explore Nature blog. It's a great blog in general and well worth a look. I especially like the end of Monday's post: "Don't forget to take a second look now and again at the things right under your nose. You never know what you might discover!" How very true.
I just discovered another Children & Nature blog, Arizona Writer. The photos are terrific. I'll definitely be following this one!
