Let your clients know about the 2008-2009 Leaf Collection Schedule.  It can be found in PDF form on the City of concord website located at http://www.ci.concord.nc.us/.  This is a good way to stay in front of your clients both past and present. 

And I have to mention this since I am in the process of "greening" my lifestyle.  Why not suggest to your clients that they collect their leaves and take them out to a friends wooded property or land to dump them.  They can reuse the bags multiple times during the fall.  Just a thought!
