Thanks to the mega storm that took down multiple trees, there's a monster pile of free wood chips in the parking lot on the north side of Lake Nokomis in south Minneapolis. Lots of people were out with shovels taking advantage of it today, but I'm guessing it will be replentished often, given the sheer volume of trees yet to go through.

 

The wood chips are often on the larger side of wood chip mulch, and it's not the same quality you get in bagged form, but the price is right and it's locally sourced.
