I've never hunted a particular rub line. Generally where I hunt you don't get very many distinguishable lines. 1.Because so few bucks make it to maturity
& 2. the higher deer numbers leave you with an absolute random splattering of rubs everywhere. I'll find groups/areas of rubs, more than actaul lines. For killing any buck that is a good method to use. Lots of times it is in subtlle funnel type area.
