Somewhat warm and relaxed before the ocean plunge the week before last in Quincy for the John Hancock Birthday Plunge are Greg McMillen, Terry McMillen, Marie McDonald, and Erin McMillen. The girls are wearing the lobster headgear to advocate giving up eating lobsters. The January ocean plunge raises money for local charities and is a really fun event. Some of the swimmers, shown below, after the plunge coming out of the water was originally shown on Quincy Daily Photo.
Like yesterday's doorway, this shot was taken at the Christian Science Center. You can see a different view of this space here.
One of the hazards of living or working in the city in winter is the risk of getting hit by falling ice. I don't remember seeing signs like this years ago. My guess is that lawyers must be telling building owners and managers to put out warning signs to limit their liability in case of any injuries. I wonder if anyone has been injured walking into, or tripping over, such a sign and sued the building for negligence?
Looking towards Cambridge from near the Hatch Shell. Longfellow (Salt and Pepper) Bridge in the distance.
A walk over Storrow Drive on the Arthur Fiedler Footbridge provided this view of some great looking clouds on a below freezing afternoon this week. Visit other skywatch Friday posts.
Named after Jamaica Plain beer baron Theodore H. Haffenreffer (l880-1956). His presence on the Park Commission from 1930 to 1956 resulted in granite tablets placed by the main gates of the Boston Public Garden. The connecting pathway over the lagoon bridge was dubbed "Haffenreffer Walk" during the administration of John Hynes in the late 1950's. The tablets' last lines proclaim Haffenreffer's "Lifetime of dedicated service to his native city," a rare tribute to the many, many German immigrants who have passed through the City of Boston.
This is a view of Boston Common from Beacon Street looking towards the Park Street Church (spire in the background). This photo is due to the prompting of Chuck in Seattle who asked for a winter picture of Park Street. I couldn't post the same scene, so I settled on one that shows some of the Holiday lights on the Common trees and "sort of, almost" satisfies Chuck's request.
This week's monochrome Monday shot is of a bench through the glass of a bus waiting area.
View looking down Park Street toward Tremont Street. Park Street begins at the top of Beacon Hill, at the intersection of Beacon Street, where it is lined up with the front of the Massachusetts State House. It borders the Boston Common on the right (west). This is the view looking up Park Street.
