I've only been to Dick's one time, when Wal-mart was out of the ammo I needed. Guy behind the counter wasn't even remotely friendly, the ammo was SEVERAL dollars higher than anywhere else I've purchased it, and the store was weak tea compared to Bass Pro or Cabelas.
I have no problem not going back.
This is the first time I recall national chains reacting like this though. Add that to the serious anti-gun sentiment I'm seeing all over the web and tv and I'm getting a little concerned.
