I'm loving the tangents this thread has taken. Some of the most fun, informative, thoughtful posts I've seen on a thread in awhile. Like pdqdl reminds us, he is an arborist. Many folks on here are. It's arboristsite after all. Shouldn't be a surprise that we're not all chainsaw hacks and that there are a lot of educated people on here with serious tree knowledge. But doesn't always show itself. "Educated" has become a bad word in some circles that people associate with elitism or academia, but it just means you've learned information and processed it, it doesn't have to be from school. When I was living in Mexico, I was telling a Mexican friend I couldn't believe one of our "educated" neighbors believed the myth that if you put a full plastic water bottle on a lawn, dogs wouldn't poo there. My friend corrected me - "Rafa went to university, but he's not educated."
