Life in the desert—where Bubby and Baby Mac live—is a wee bit different from life in the mountains—where I live and where Bubby and Baby Mac's mommy grew up. For one thing, it's often too hot in the desert in the summer time for kiddos to play outside. Seriously too hot. As in Extreme Heat Warnings from the National Weather Service hot.

That certainly doesn't mean, though, that there's no fun to be had.

When temps get too hot and high in the desert, folks simply take the fun indoors. They forego sizzling playgrounds and descend upon indoor play areas instead. Air-conditioned play areas.

One of Bubby's favorite indoor play centers is called Imagination Avenue. We visited last week, and he certainly exercised his imagination while there.

He imagined himself as a policeman, a fireman, a doctor, a grocery shopper.

He also baked cookies and cupcakes, worked puzzles, played school. And he built houses and boxes and a tunnel for taking a break from the workout.

With so much to do and the myriad imaginative options to explore, the fact we couldn't play outside no longer mattered one single bit. Not to Bubby, not to Megan, not to me.

Not even to Baby Mac.
