As kids, we used to round up scrap lumber and pallets and set up apposing forts about 25 yds apart in the back yard. Then we would duck for cover and pitch recently fallen black walnuts at each other.
Mom was not happy when she saw my previously white T shirt after taking a half dozen hits from fresh juicy walnuts.
In college I took a lab class where we found various uses for plants growing wild. Some of the ladies died woolen yarn and wove tapestries. I was amazed at all the different colors they managed to produce from different treatments using walnut hulls.
