What areas of the country have the most dealers, most collectors and best collections?

I am sure the hobby (and its different components) are not evenly spread out across the fruited plain; and are instead concentrated in specific areas. Which areas of the country are we talking about (large metropolitan areas vs. smaller areas; east coast and west coast v. flyover country)?

In modern circumstances the coastal cities tend to have the largest concentration of dealers/collectors. Why, because people naturally like to live near coast lines!
