Today was a long-waited perfect day off without restraint. Even if I got days off, I have to carry my smartphone for communication with the ward of my office, but today was fully free from work. My wife and I went for a drive to see a big cherry tree which belongs to the kind, "Edo-higan". Its age is said to be more than 300 years. The worldwide well-known cherry trees are the variety called "Somei Yoshino". The cherry trees planted along the Potomac are this man-made kind. "Edo-higan" blooms a few weeks earlier than "Somei Yoshino".
