We are unforunately devoid of large, got everything places like that around here. I get most of my shooting stuff at Midwayarms. There are a few small gunshops scattered here and there but nothing really worth driving for. If you did, they probably wouldn't have what you want but would be more than happy to order it for you (I can do that from my computer chair and save the drive and markup). Bob and I make the rounds on a lazy saturday sometimes but it's more for entertainment, not because we actually expect to find something specific. Wish I lived close to one of those huge Bass Pro or Cabela's stores. That would be interesting.
