I dunno. I don't see the benefit of a "Black Rifle" room on THR.
I'm the quinisential EBR owner, and I tend to gravite towards the forums that are EBR oriented. I'm a member of so many firearms forums that I've forgotten half of them. I regularly post here and on the Saiga forum, but go to the AKfiles, and SurplusRifles often.
Another forum has a way of dividing the community, to a degree. While I may not have a specific interest in someone's Marlin lever action, and they may have little interest in my AK, I do tend to read threads about rifles I don't have a particular interest in here. I am sure the Marlin guy does, too. That has a way of allowing those of particular subsets to learn more of other rifles that they'd not normally think about, and has a way of creating more cohesiveness rather than division.
Who knows... as I learn more, I may need to toss a lever rifle in my gun case!
The High Road is a great place for all lovers of firearms whether they are EBR owners or traditional sporter owners, hunters, or paper-punchers, competitors, or plinkers to all come together and share our interest, knowledge, and enthusiasm with each other.
