chrisb, what a lovely flat. The setting looks very peaceful.
It is, thank you (except when the wind is roaring around outside as it is now!). It's miles from anywhere really which has its minus and plus points. Also quite small, damp n draughty inside and expensive to heat!
Here is a nice aerial view of Serpent Mound in Ohio. I haven't been there in a long time--may have to make a trip soon.
that's a familiar, hand-tinted picture - looks like one i scanned from a book and used as computer wallpaper back in the 1990s. it's been almost that long since i've been there, too. fantastice place, very special to me going back forty years or so.
I've not seen much of the Mississippi; from the headwaters in Itasca State Park in Minnesota (you really can walk across the river) down to around Davenport, Iowa, about 560 miles. That stretch is relatively calm. Maybe it's wilder and rougher further south.
An elderly woman I once knew talked about walking across the river in late summer (when the river was low) when she was a girl in the same area where I took the photograph. This was long before dredging and barge traffic. Now days, from the same spot, I enjoy watching the tugboats moving 12 or more barges at a time up and down the river - it's quite a sight to see.
