From your arial photo are those real dark green areas trees and forests?
Yes... Those are plots of timber. I think what I'm gonna do based on everyone's advice, is get there before sunrise, sit in the middle of the field and listen for a while. Then once the sun's been up for a while I will go around with my bino's and do some glassin of the different fields. I will also walk along the creek and look for tracks. Thanks to all for the help so far.
