This tree noticed the neighbor’s dock pilings had received an arch on top.
I’m not sure when this happened – it was done somewhat sneakily. One day, no arch. Another day, arch. I guess it was done via boat – that’d be necessary to get access to the pillars. So they left no trace and I guess it happened when I wasn’t around or wasn’t paying attention, and Art, of course, is deaf enough these days that he probably wouldn’t have heard or noticed unless he happened to look out.
