This is a great time of year to encourage grandkids to enjoy the natural world.
Nature guides are one way to do this. Check at your local bookstore for the laminated, EZ-fold type of nature guide that fits into a pocket easily, and choose one that a grandchild might use to identify trees, birds, or flowers.
Or visit your local bird-supply store for a CD of birdsong that helps listeners identify which bird sings what.
Purchase one for yourself and one for your grandchild, then share the adventure.
If you live at a distance, send your grandchild one guide, keep one for yourself, then write an e-mail note or send a letter describing the trees you've identified, or the flowers you've found with your copy of the guide. Ask your grandchild to let you know what she's found, and how she uses her copy of the guide.
It's just one more way to share an experience and stay in touch, all at the same time.
