I like #165. I wonder if it could be simplified or cleaned up a little more so that the graphics stands out and is more brandable. The farm scene looks a little crowded and off in the distance.
Great idea though.
I think #179 is hysterical! But not for the logo (-:
Thanks for the ranking & feedback, here is a cleaner version of the farm. Please let me know if you would like to see any font and/or color variations.
