From subways... but... why? humidity pumped up there? Speaking of subways... Montreal subways are MUCH more smoother than NY's :S... NY's seem to be guided directly with the rails; here they have big tires that kind of roll on the rails And the trees are alive... with leaves and we can see the green skin... but they just don't have any bark. In fact I find it weird that they actually live without bark ; I'd think that bugs would eat the crap out of it in no time. I have no idea why but its from the subways. If its an asian long-horn thats eating the tree, they would take the tree down and burn it.
