I have a large quantity of cedar siding that was installed on the
exterior of my home, and which is being removed (don't ask, long story).
It's not treated, painted, or stained.

Assuming I pull all the nails, can I turn it into good mulch for the
neighborhood? I hate to waste it, and pay $400 for a dumpster in the
process! If it can be used, any recommendations on what kind of
chipper/shredder I'd need to rent?
