Sawdust needed for Community Garden

The new Park Slope/Gowanus community garden, GreenSpace on Fourth (4th Ave between Union and Sackett) is starting a composting program and is seeking a local source of ‘brown’ materials to mix with the ‘green’ food scraps. The ideal brown is sawdust. I wonder if any of the people who regularly read this forum might have a regular supply of sawdust they’d like to get rid of. We could come pick up from you on a regular basis. Thanks Moderator – i know this post is only tangentially related to the intended focus of this forum. If it is not suitable, please let me know. Thanks.
