Was finishing a driveway off Mesa Drive last Tuesday and the bubble kept dancing around, so I set the screed by feel and called it good, then the homeowner came out and pointed at this 2 inch low spot near the garage like a hawk spotting prey. Spent an hour feathering in a patch mix and now I bring a string line on every pour, anyone else ever get fooled by wind on a big slab?
That "bubble kept dancing" line sums up half the stuff I deal with in life. Wind, bad luck, or just a Tuesday, seems like the universe always finds a way to mess with your best guess, so I've learned to double-check everything that can shift.
