If you are really going in blind, u better have a lightweight pair of boots with good soles, a pack with a water bottle and snacks. First thing i would do is get elevation. Use google earth to find a likely atrea u want to hunt, then loacte the best listening vantage point above that ground. Climb up there well before daylight and listen. Take a map with you and take a few mins and as birds sound off on the roost, mark their locations on the map. Every bird u hear. Then pick one to go after. It will be a slower start to your hunt, but its the best way i know to speed scout last minute. Id stay at the vantage point till flydown that first hunt, to hear as many birds as possible. If you strike out, move on. When u have limited time to hunt and no time to scout u have to move till u find the birds.
