We soft toss wiffles with a small wooden dowel (broomstick size) into the Stucco. Seems that this stuff is pretty durable. The small bat forces you to find the sweet spot. As a renter I hope we don’t damage the stucco, but my guess is these wiffles won’t because it’s too tough and the balls just bounce off.
Some would say to go to a park for this stuff but good luck finding an open park where you can play a little ball. Be glad you have a place where the kids can play I know I am.
