Sounds like a ton of fun crush.
In my youth we use to play corkball, kids vs parents. The old fashion way, cork from a wine bottle wrapped in white surgical tape. Man you talk about making that thing dance all over the place, it puts a whiffle ball action to shame and then try hitting it with a broom stick. Great way to build eye to body coordination.
We were too poor to have a tee, but dad spent countless hours pitching to us with the old corkball. Made the baseball look like a beachball in real games coming to the plate. ( I always wondered where dad got those corks, he doesn't drink )
