So the husband and I both used to play tennis but neither of us have played in almost fifteen years. For our whole marriage once or twice a year, we're both like "We should so do that" but never get around to getting rackets and such.
Well before Christmas I was picking up kiddo more train tracks at Ikea, and they have two rackets for $17! Don't get me wrong, they're on the cheap side, but we've been having a blast.
If we stick with it for a few months than a real equipment investment might be in our future.
