This subject comes up over and over, and the original poster usually takes one of two directions. Either they give up, lamenting the 'fact' that they live in a dusty wasteland, or they spend more time reading the board, modify their search, and keep hunting. Successful dusty hunts don't come easy, and they don't come often. For every post you see detailing some amazing haul, that person has likely spend dozens or hundreds of hours in fruitless pursuit.
In my case, I was only successful when I was in an area of town where I had good cause to fear for my safety. I have Mexican friends who live in the Mexican ghetto, and they are afraid of the areas I hunt. Find a place like that, get out at 9 am (yes, they are open) and hit EVERY store you see. You also have to know how to identify dusty bottles through bullet proof glass. I suspect that many dusty hunters pass by good bottles for lack of knowledge.
Dusty hunting without a guide reminds me of bird hunting without a dog.
