Hi Terry,
Some years ago, a friend lent me the 1908 issue, and I found it fascinating. The discussion here about interpreting the WW&F Railway Museum mentioned the effect of railways on early 20th century life. That recalled an advertisement that I saw, perhaps in "In the Maine Woods." The text of the ad was something like, "Why drive 11 hours to Millinocket when you can board the sleeper tonight and awake there refreshed in the morning."
Another advertisement of interest was one for Attean Lake Lodge. As you doubtless know, this is one of the few still in existence today, and it is still owned by the same family (Holden)! I have paddled by it a half dozen times, and staying there is definitely on my Bucket List. I sent them a photocopy of the 1908 ad, but never heard back.
Evidently there were dozens and dozens of sporting camps (Antlers Camps, Chairback Mountain, Libby's, Packard's, etc.) and hotels that catered to rusticating "sports." While there are still a lot of those places, there seem to be many fewer now despite better roads and vehicles.
