What a wonderful playdate! We have bison around us too. They mostly keep to the forest and only seem to attack stupid tourists. That's unfortunately given them a bad reputation, but they are fantastic creatures. An entire herd lives in the forests behind us and we've crossed paths a few times which was quite the sight. It's so good to know the children are playing outdoors too. As fun as video games may be, in my opinion every kid needs to climb trees, shim knees and play using their own imagination rather than pre-packaged imagination. Great post!
