Here’s a great PSA for the week. Cast in stone, no less.

The story behind this rock: Roger Babson (1875-1967), remembered today largely for founding Babson College in Massachusetts, was an entrepreneur and business theorist in the first half of the 20th century. He also founded Webber College, now Webber International University, in Babson Park, Florida.

Babson was interested in the history of an abandoned settlement in Gloucester, MA, known as Dogtown. To provide charitable assistance to unemployed stonecutters in Gloucester during the Great Depression, Babson commissioned them to carve inspirational inscriptions on approximately two dozen boulders in the area surrounding Dogtown Common. The Babson Boulder Trail exists today as a well-known hiking and mountain-biking trail. The inscriptions are clearly visible. The boulders are scattered, not all are on the trail, and not all of the inscriptions face it, making finding them something of a challenge.
