I'll also add it depends on how bad they've spooked. Bad spook = no stop at tree line/brush line and keep hauling. Moderate spook they'll often pause once in the tree line. look for a few seconds, and continue running/trotting. Light spook and they'll often go to cover and hang out, and come back if everything seems cool...or they'll move off. In listening on bad spooks, they'll go 100+ yards into cover before settling down.
