Laser every time now, my string line sagged over a 30 foot run once and I tore out a whole patio base because of it. That bump in Lubbock sounds exactly like the kind of thing that sneaks up on you with the old method lol.

Honestly the waste tax always kills the savings, gotta plan portions first.

You ever try to check for glow? My friend Kate bought a bunch of those old apothecary bottles at an estate sale, all excited about the cobalt blue ones. Took em home and hit them with a UV light, and half of them glowed bright neon green under it. Said it was a dead giveaway the newer glass has that manganese reaction or something. She was so pissed she drove back to the sale but the dealer had already packed up and left. Now she carries a little keychain UV light everywhere she goes, says it's the only way she trusts anything anymore.
