I dunno about high end...Any one that carries Simms or Patagonia or Orvis is high end....Did I say Simms? Cabela's has them now...but at least they don't hold their noses in the air like a couple of the fly shops that I have visited in Colorado.
Granted they did wait on me and I did buy some flies from them, but conversation was out since I wasn't ready to book a trip or buy $1000 bucks worth of gear.
I'm not a big spender. Never have been, but I DO like conversation. AND, the fly shops at the time that I visited were NOT busy.
