Blacktail can be hunted many ways, you get to decide which works for you. My previous strategy was locating does I saw consistently. They were essentially in a 50 yard zone every day. Id wait til the last week of Oct and walk to each spot and glass them up. Eventually they would have a buck on them. On a good day, a hot doe can have 5+ bucks circling and watching the behavior taught me a lot. I call this my previous strategy because more people are walking than ever and most of the deer get bounced.
I now still hunt timber edges and benches. It can be agonizing to go as slow as required to see a Blacktail buck before it sees you. If you go faster than step, glass, step, glass, you will either see them running or they will slither away without you ever knowing they were ever there.
Be prepared to get addicted. Once you see a white faced buck all you'll want to do is find another one.
