Thanks Rainman...
That mix sounds perfect for what I'm after. I am currently dismantling a used tractor combine salvage yard that my family owned for 60 years. I am the proud owner of 60-75 tires of various sizes (some huge) to dispose of. Have seen some cool ideas here on Pond Boss and plan on implementing all of them. That said, can I assume that the CC stocked will need to be single sexed?
