Backhoe clipped a gas line marker I missed, now I double-check everything

Was clearing the lot for my new build and got too eager with the excavator. Didn't see the little flags for the gas line and nicked the marker post. Luckily, no damage was done, but it gave me a real fright. Called the utility company right away, and they came out to confirm it was safe. Now I always walk the site with the plans before any digging, and it feels like a big step forward in being careful.
