Sawdust (Severna park)

Hi I’m sure some of the woodworkers have a full dust collector that needs emptying. I make fire starters and i’m out of sawdust. I’m looking in the severna park area near Giant. If further out we could meet at the royal farm on Ritchie hwy because I don’t drive anymore so I go where my bike will take me. A white kitchen bag full would keep me going for a while. Thanks for the help
