Step 1: Tear out and repave an 8 ft wide strip the full length of runway (10,330 ft).
Step 2: Put temporary centerline paint on it... no reflective beads yet.
Step 3: Let it cure for 30 days so the cuts are neat and clean.
Step 4: Re-saw the 1/4-in deep grooves. And do it 1 ft at a time.

Yup, that's 10,600 passes with the machine you see above.
Final painting and application of reflective beads to follow.

I'll be sleeping during the daytime a while longer yet.
