Went to my grandparents’ house Saturday. Got grampa to pull out the trebuchet he’d built with my cousin. We launched tennis balls filled with dirt quite some distance. Then I put a fist-sized rock in and it launched mostly upward and landed on the metal beam of the hay loft, frightening the horses. Then I realized what you don’t have in the city…space. Space to launch projectiles great distances and make lots of noise. We also did some target practice with the slingshot. I can hit a box. Yay.
