As I was cleaning out some old papers tonight, I came across this great article on what we as kids we call helicopter seeds. Those seed pods that are found on our old friend, the silver maple early in spring and then by summer, on our driveways and our yards.
Our house here was actually has surrounded by three of them until recently. We lost a large limb from the one in our back yard and unfortunately we had to have the tree taken down. I love trees, as many people know but the limb you see, fell our our house and that was a problem.
