I did some volunteering with Trees Atlanta recently. In one of their offices they had this 10-year-old map of the Atlanta Beltline, with plans for the surrounding landscapes. Very cool to see this early vision – and a different one than the neighborhood/transit-focused one we’re used to – back when it was mostly just a dream. It still is, but it’s also on its way. I like that they still have it around.

A knot is the basal portion of a branch whose structure becomes surrounded by the enlarging stem. Since branches begin with lateral buds, knots can always be traced back to the pith of the main stem.
