Question about using a water-based finish over oil stain

For years, I was told you could not put a water-based polyurethane over an oil-based stain without a mess. My old boss in Grand Rapids swore by using an oil-based topcoat every single time, saying the water-based stuff would not stick right and would look milky. I finally tried it on a small maple cabinet door last month, after the stain had dried for a full 72 hours. I used a light coat of General Finishes water-based poly, and it went on perfectly clear with no issues at all. The finish is hard, clear, and has held up just fine. It saved me a ton of cleanup time and smell. I guess the old rule was based on older products that weren't as good. Has anyone else switched over and found the same thing, or did I just get lucky?

The day they took down our flyers for a campus debate

Last semester at my state school, a student group put up posters for a debate on tuition costs. Campus staff removed them all, saying they needed 'prior approval' from an office that takes three weeks to answer. It felt less about rules and more about stopping the talk before it started. Has anyone else seen a simple event get shut down like that?

That one rock ledge in my own backyard nearly beat me

I know a lot of guys swear by just digging out any rock you hit, but I ran into a solid limestone ledge on a simple backyard privacy job last month that changed my mind. It was only for a 40-foot section, and I figured I'd just chip it out. After two full days with a digging bar, a rented demo hammer, and a lot of sweat, I'd moved maybe three feet. The rock just kept going deeper and wider. I finally called a buddy with a small excavator, which felt like giving up, but he had the holes dug in under an hour. What I thought was a one-day dig turned into almost a full week of fighting it myself. Sometimes the old school way just costs you time and money. Has anyone else had a rock problem that made them switch up their usual plan?
