With three days of wet weather we've been getting out when we can. Rather than getting out lots of gear only to have to put it back again with the next shower, we've been making use of the bounty of nature. In this case falling acorns and leaves. We started aiming at the post then, moved back, then shifted to a leave stuck in the post as with practice our aim improved. We had to learn not to get to close as sometimes acorns miss or bounce back and hit us. Several children are now hitting the leaf from several meters back.
