It might pay to clear some scrub trees and plant a nice hybrid oak tree:

A few trips out to it with some water for the first few summers can go a long way toward getting it established. Once the tree is mature - it puts out a ton of acorns.
I had an English Columnar Oak that normally doesn't produce acorns for the first 10 years, produce acorns after 3 years, had a big crop in years 5 and 6.
It's kinda like those complex salt licks - maybe it doesn't get you a deer the first season you do it, but it pays off over time, especially if you are taking your kids hunting.
