In the summer months, Bud and I try to do our small piece to reduce the size of our environmental footprint by rolling down the car windows and keeping the AC off as much as possible. Bud calls it "having fresh air." The only time we forgo fresh air is when we'll be traveling at high speeds, when we know that: 1) the strong wind whipping through the windows will send our compact car flying all over the road; 2) the strong wind whipping by us, but still within reach, will prove to be too great a temptation to keep small hands and faces inside the car; and, 3) the strong wind whipping past our ears will make it impossible to hear the music on the radio - always one of the highlights of any car trip.
And so it was yesterday, as we pulled onto an on-ramp and Bud asked, "Can I have some fresh air?"
"Not right now," I reminded him, "We can't have fresh air on the highway."
"Just on the what?" he asked.
"Just on the ---" I started, then paused as I searched for the right term.
"Just on the low-way," he offered.
Yep. That'll do.
