One other observation from the perspective of the young side - you're probably noticing that the investment horizons, where to substitute labor for capital (ie, spend money instead of doing the work, or vice versa), cashflow needs, etc are different for you and for your dad. 

Again, I think the known solution in the ag world is to have a business structure that can more effectively address all of these things, and often that is not merely a simple partnership.  Simple questions like 'when and where and how do we upgrade/build infrastructure that has a known positive ROI' aren't so simple when the benefits and costs aren't necessarily distributed equally, but may create perverse financial incentives.

Just my HO.  As always, do as I say, not as I do.
