I have some friends who think posting ultrasound pictures online is inappropriate/tacky/creepy. To them, my apologies (and permission to skip this post).
To the rest of the world, check out this beautiful leg!
The ultrasound tech said it's the thigh of a soccer player. Or runner. I know a certain proud grandfather who'd say it's the thigh of a NASCAR driver. (Regardless, the child can thank Matt, since mine are the thighs of a speed skater.)
