I call them Sickamores. Sometimes they'll make my throat close up. I think it depends on the time of year, but there is definitely some thing in them that makes you cough and choke. I seen ground men almost die chipping them. But other times they don't do anything. Iv'e always wondered my self what was up with them. Beastmaster
Sycamortis! The effects can last a couple of days, even eating and drinking doesn't take away the feeling that you ate fiberglass. I was in a london plane tree just the other day, tough trees and seem always to need minimal work as far as pruning
