@jude07 Here's an idea (I was walking a DNR trail in Northern MN this morning) - those big round burrs make great natural "legos." Tomorrow I will grab a bagful to take home for playing with my grandsons. When I was a kid, we made dolls, clowns, towers and lots of things from them with my Grandma. The spines on them cling to each other, but don't really poke fingers. We also collected milkweed pods to dry & blow the seeds away. Just be careful of the poison ivy - it is everywhere this year - even found some in our local city park and had to call maintenance because it was near the disc golf basket.
