Kim hosted this play group on camping.  She went all out.  We read stories, sang the bear hunt, had beans and hot dogs, and even smores.   
We had great centers too.  There were tents out with play food to prepare, searching for snakes other critters embedded in the rice and bean, and even fishing poles to catch a fish.  My kids were too excited to complete the nature art project.  What a great time.  Thanks Kim!
