Fly Fishing Flies by Regions of the Country

I know I would add the bugger and the grey ghost streamer to the South Region for sure. Take a look at your region and see if the flies listed are the ones you would actually be using. In other words have these guys pretty much peg the flies for all the regions?  Check out your region
