Your Mother is always with you

Your Mother is always with you. She’s the whisper of the leaves as you walk down the street, she’s the smell of certain foods you remember, flowers you pick, the fragrance of life itself. She’s the cool hand on your brow when you’re not feeling well, she’s your breath in the air on a cold winter’s day. She is the sound of the rain that lulls you to sleep, the colors of a rainbow, she is Christmas morning. Your mother lives inside your laughter. She’s the place you came from, your first home, and she’s the map you follow with every step you take. She’s your first love, your first friend, even your first enemy, but nothing on earth can separate you. Not time, not space, not even death.

Holland Tunnel opened

In 1927, the Holland Tunnel opened for vehicular traffic as the first twin tube subaqueous vehicular tunnel in the U.S. It joined Jersey City, N.J. and New York City, N.Y. The day before, after an opening ceremony, in the next hour 20,000 people walked the 9,250 feet length of the tunnel from shore to shore, of which 5,480-ft runs under the river. Named after its engineer, Clifford Holland, the tunnel carries 1,900 vehicles per hour. The air in the tubes is changed 42 times an hour, at the rate of 3,761,000 cubic feet per minute. The first subaqueous highway single tube tunnel in the U.S. was the 1,520-ft long Washington Street Tunnel beneath the Chicago River in Chicago, Illinois, which was first authorized 17 Jul 1866, though it did not carry automobile traffic until 1911.
