That is a very important question that could and should make our research better if we can get others to share what they know.
Here is what I know of, taken advantage of, and look forward to seeing in the future.
Bay Area
The Fairway Magazine- BAy area and Pacific Coast
Pacific Coast Golf and Motor (numerous variations)I have more info, but I am on a vacation now. Would love to see more of these magazines!
The Country Club- More on SoCal and Pacific Coast
Pacific Northwest Golfer- Mostly in the NW but also covers CA
Midwest
The Golfer- based out of Chicago, covers the whole of the US but is hard to find. I would love to get my hands on some more of these earlier versions.
Hope to see some more additions!
