Historic Old Northeast Neighborhood Association

In my runs & walks through the neigborhood I have seen multiple homes with ''excess'' hex blocks stacked somewhere on the property. I am not talking about blocks temporarily pulled-up to repair city sidewalks! I am in the process of re-doing my front walk and need more block than I currently have... particularly red/green/gray block. If you have any that you are willing to part with - please let me know. Thanks! Chuck
