I'd say it's time to scout them out! Are those crop fields on top? You've certainly got the right prevailing wind for potential bedding on those points in the thermal tunnel zone. Knowing you, you've probably already done some recon on the area? If those points don't pan out I'd check the heads of those draws for travel and or bedding if there's good cover.
On the two points that I checked I found small rubs close to the ground that are healed over?????? No fresh rubs on the points, maybe some beds. Its been awhile since we have had a south wind for very long, and there are lotsa leaves. I will post some pics soon.
