This deserves a special post:
What is International Rock Flipping Day? It is a blog carnival to celebrate all those critters that live under rocks, as well as the naturalist spirit that drives you to look a little deeper.
How do you participate?
Basically you go outside and look under a rock or two. Record what you see by drawing, painting, taking photographs or recording in your nature journal. (If you live where there might be poisonous creatures under there, like scorpions or snakes, you might want to use gloves and/or a bar to flip the rocks.)
When you are done, carefully return the rock to its original position.
Then blog about what you found. out.
I will have more information about more information about where to send your posts as the date approaches. I believe Wanderin' Weeta will be hosting.
Edit: Yes, Wanderin' Weeta is hosting and you can get the full scoop now.
