You can get the chocolate wafer cookies in a sleeve in the dessert toppings section of your grocery store. Don't bother looking for them with cookies - they're never there! Somehow, they've earned a place among ice cream toppings, and ice cream toppings only!
"In all our woods there is not a tree so hard to kill as the buckeye. The deepest girdling does not deaden it, and even after it is cut down and worked up into the side of a cabin it will send out young branches, denoting to all the world that Buckeyes are not easily conquered, and could with difficulty be destroyed." - Daniel Drake, 1833
