Log: Recovered in good condition on 4/7/2023 while visiting Springfield. We visited the Lincoln museum and Oak Ridge Cemetery, and enjoyed good food and beer at Obed and Isaac’s before making the long drive to Midway to fly home. Not my first time visiting Springfield, and likely won’t be my last. The photo below was taken from several blocks away and cropped.
This is my first stab at logging a benchmark recovery here. I am writing this on 5/10/2025, and will attempt to backdate the post to the actual recovery date.
