This is the monster grinder used to make the mulch.
The Capen Park Mulch Site is a location where you can drop off yard waste and get free mulch. Compost is available Wednesdays from 1:00 p.m. to 5:00 p.m and on some Saturdays at $12.00 plus tax per cubic yard with a loader on site to assist.
Unfortunately some people abuse the system and dump waste and trash. Tires can be particularly problematic to get rid of and here you can somebody took advantage of the situation. One problem with tires is that the city trash service will not pick them up unless they are cut into four pieces which is a little bit of a trick to do. I have a lone tire sitting in my basement, one I inherited from my son when he moved out over two years ago, to attest to that fact. So, people look for alternative means to get rid of their old tires.
I highly recommend the composting workshops which are scheduled periodically. Here is the information from the Compost-Mulch Operations web site:
Fall and Spring compost workshops are held at the Capen Park Demonstration Site located off Rock Quarry Road. For additional details about the compost workshops, call Columbia Public Works at 874-6271, or send your name, address, telephone number and E-mail address to pw-volunteer@GoColumbiaMo.com, and we'll send you the composting schedule and information you requested.
There is also a lot of pretty scenery in the area including the walking trail that runs right on the north side of the site. As you head west along the trail you pass the compost class site and eventually come to an old bridge which is just used now for bicycle and foot traffic.
The picture above and below are views from the bridge.
