I think we saved the best for last. On our way back out of the Midcoast, we made two lovely stops on a beautifully sunny day.
First up was the Beech Hill Preserve in Rockland, which doubles as a working organic wild blueberry farm. This spot was recommended by a coworker of mine, and has some stunning views. It's also far less trafficked than Mount Battie, thanks to the fact that you have to do a (rather gentle, if you're not carrying a toddler on your hip) hike up to the top.
Finally we stopped at the Olson House in Cushing. Here I'm glad that Mr. Cleaver had me do some reading up on the Olson's and Andrew Wyeth's relationship with them. Without context, the Olson House is nice, if a bit dull, as it's basically an old empty farmhouse. With context, the place has a lot of resonance.
I mostly read the 1982 book by Betsy Wyeth, Christina's World, and the first chapter of Richard Meryman's 2013 Andrew Wyeth: A Spoken Self-Portrait, both of which I found helpful. We also picked up Andrew Wyeth, Christina's World and The Olson House at the Farnsworth gift shop. I haven't read it yet, but according to Mr. Cleaver, it tells more about the history of the house, in particular what happened after siblings Alvaro and Christina died.
After wandering the house and grounds, including a visit to the A. Wyeth and Olson graves, we drove back to Thomaston for a nice lunch at a local cafe, then it was back on the road and back home.
