The best places I have found are always on the high land side of a creek. Or any old water source, springs, the key to me is always to think what was important to an Indians survival. Southern facing slopes are always good as they warm first and keep in min they had summer camps near rivers-creeks, and winter camps near good hunting land. Like others have said as well, creek bottoms, and not to be smart, but arrow heads are where you find em. Ive found some very nice points in ditches! They are literally EVERY where. Just keep your head down, and its not how much ground you cover, its how well you cover the ground your on. Oh and a good flipping stick is a must, I have found big ones that all you could see was a speck of a flake exposed. So flip every flake you see. you never know whats just below the dirt. Good luck!!
