I’ve thought about this too. I would think tapping trees along public roads would carry some of the same risk, but it Isn’t stopping me or many others. Urine would likely color the sap so you could toss any that’s not clear. I’d agree poison isn’t likely. How about - Have the school to announce that it will use the syrup made with these trees in its meals and cooking — pancakes, oatmeal, etc, assuming the school provides meals. It wouldn’t stop a committed peepetrator but might create a little peer pressure to not mess with it.
