Delhi, India

WWCD:  What would Christaller do?  He would take all of the tailors in Delhi and impose on the network a set of contiguous hexagons.  From that he could compute the threshold and range of the service provided.  Who's Christaller?  Look up central place theory.  [2011]

Toronto, Ontario, Canada

Get ready. Temperatures are heading south, and you might need mittens. Especially if you are in Canada. So, pick your mitt now. There's still a lot to choose from. [2010]

Randolph, Vermont, USA

Covered bridge are vulnerable to all sorts of threats: fires set by arsonists, trucks too heavy to cross, floods during heavy rains, rot from age and the elements, condemnation by highway departments, and simple lack of maintenance. Fortunately, more people are now becoming interested in conserving cultural resources. [2009]

Swanzey, New Hampshire, USA

All four of Swanzey's covered bridges contribute to the town's economic base: Visitors come to walk through history and steep themselves in an idealized past. In the process, they spend money. Let's protect the river and the West Swanzey Bridge, lest they go the way of the Old Man of the Mountain. See him? [2009]

Livingston, Alabama, USA

You can see it never floods, and it's easy to tell it's not a river. It's a lake on the University of West Alabama's campus. Here is yet one more wooden bridge that has been moved from its original location to a place where it can be appreciated and conserved. [2005]

Greenfield Village, Michigan, USA

Covered bridges are valuable commodities. Henry Ford wanted one for Greenfield Village in the 1930s. He found the Ackley Bridge in Pennsylvania and moved it to Michigan. It established the idea that covered bridges could be moved to locations, often parks, where they could teach history and be preserved for future generations. [2008]

Stoystown, Pennsylvania, USA

New England gets all the attention, but Pennsylvania has more covered bridges than any other state. Somerset County has ten, including the Glessner Bridge, which was built in 1881 and is still open to vehicular traffic. Look at the effort that has gone into shoring up its foundations. Flooding must be a problem on Stony Creek! [2010]
