Remember this picture of Baby Mac I posted on February 12?

At that time, I said I thought Mac would be running marathons by the time I saw him again in April.

Well, he's clearly one step closer. Get a load of this cell-phone video Megan texted to proud PawDad and Gramma on Tuesday:

Today, March 1, Baby Mac is 9 months old. And he's walking. In addition, he has both front teeth on the bottom, and he's working on his first front tooth on the top.

What is up with this kid?

I'm a little scared to mention it for fear this prediction might come true, too, but I think Baby Mac just might be caught up and ready to enter kindergarten at the very same time as big brother Bubby.

Today's question:

When and where did you last go for a walk, for pleasure or exercise?
