@Zac chandanais ,
along fence lines surrounding farms
This is true, farms can be replaced with, parks, parking lots, houses, lightpoles, gaurdrails, baseball diamonds, and, anywhere the wind stops blowing.
I was just in a gangway for work, there were piles of the little seed pods. (see Next Years Baby Elms)
And no short of 100 of them sprouted with a couple true leaves already.
I think it was Shaunleuw who posted the pic of the parking lot full of em. Take a look at that post. Pretty soon, the telltale overgrown whips will catch your eye EVERYWHERE!
