Sounds like you are all set. Get your muzzleloader good and accurate, and then if you don't mind trees,
go up (I like tree stands) and watch your plots. When that monster comes out, relax and take your time. You only get one shot so make it count. The thrill is hard to explain, but I wish you the best of luck in connecting with a monster Whitetail. Then make sure you do not fall out of the tree from the excitement...
