Like you I recall the vast fields of soybeans and corn in Dallas County during the late ‘70s and early ‘80s, and I can still remember the all the hardwood bottoms producing an abundance of white acorns. Now the agriculture is mostly pine, and the hardwoods have been harvested and not replaced.
Some would contend that deer meat tasted better back when deer were able to feed on more hardwood forage like white acorns and had more soybeans and corn to eat. Pine woods forage and food plots with oates, wheat, vetch, etc. do not produce as a high of quality of meat some would contend. Your mileage may vary.
