Tennis without a net

I just learned about this organization, Project Tennis Backboard, who tweeted about my tennis poem. They raise money to put tennis backboards in communities. On the site, a Stanford University tennis coach says, "It’s almost unbelievable how many players have learned tennis and sharpened their games ‘against the wall’!! I must admit, I think the wall is still undefeated…." Maybe he'll change his mind after he reads the poem!
