"Mature" trees...that just means big and old.  I have a really "mature" tree at the back corner of my property with more leaves than you could possibly count.  When November arrives, it translates to a lot of raking for me but it means a whole lot more for the kids.   After a whole lot of raking, then the real fun begins.

I captured some video with my phone...Vicki joined in the fun...hope you enjoy...they sure did.
