Amigo, you won't find much cool in the way of merchandise in Flag, although you might check out the Beaver Street Brewery.
Derek is doing his thing, but he's basically a FAL guy. The gun shops suck for the most part, especially as far as evil assault rifles go. Ruff's and Gary Reeder's are the only places I am aware of and you won't be sending postcards home talking about them. If you want to see cool stuff, go to Prescott and visit J & G and Prescott Valley Guns.
