The gorgeous sunset. The golden straw. The delicate aroma of horse manure, floating on the breeze.
We were actually set up to shoot a tractor driving down the path on the far side of the muck heap, but those were some really dedicated photographers.
We actually had a guy sink in the pit the next day- he got armpit deep with one missed step. Poor guy is pretty tidy on the worst of days, and I have never seen such determined denial on any man's face before or since.
And the less you know about cleaning a tractor while getting shots in a muck heap, the happier you'll be.
