Tennis anyone?

Soo…I am planning on going to the park to get some exercise and plan on taking a tennis ball for some exercise motivation. I figured 1) Compact 2) Guaranteed to land (at some point or twenty) several feet away from my hand, whereby I am forced to retrieve it thus, getting some real activity for once. and 3) The one thing I can afford right now. (Thanks work mom for giving me yours!)

I just got a slightly hilarious image in my head of myself as a Labrador Retriever. No, I will not be carrying it in my mouth.

Stop laughing Lori.
