Hey Christie!
Although you say your idea would cost me nothing, the engineer in me wonders...
Assume an average individual with an average bladder would take care of a cubic foot of compost. That would mean that to get the job done before Spring, I would have to recruit what few remaining friends I might have to come by my pile and help me out. Say I would have 30 friends that wouldn't recoil in horror, and actually turned up for my Nitrogen Party.
For a compost pile of 240 cubic feet, that means each of my friends would have to contribute 8 times each. The only way they could accomplish that Herculean feat is for me to supply them with almost endless amounts of warm beer on my dime. Kegs maybe. My friends have always loved my free beer!
Hence I wonder at how much your "cost free solution" to my nitrogen problem would actually cost me in the end.
And I thought gardening was supposed to be a relaxing pastime.
