“According to the Insurance Institute of Highway Safety, modern roundabouts — which have proliferated in this country in recent years — are not only far safer than regular intersections, they are also more fuel efficient. Drivers use about 30 percent less gas when using a roundabout compared with a traffic signal, according to the Institute, because they don’t necessarily have to stop and idle.” - NY Times
This roundabout is located in South Berlin, Massachusetts where River Road West, Whitney Road and South Street converge. Just a few short years ago this area was undeveloped farm land owned by the Risi family. Much of the land remains grassy fields which were once used as a grazing area for as many as 80 dairy cows. The farm land was purchased in 2010 for mixed-use development, and some construction has already started. As part of the land-purchase contract, the Risi family and town residents requested that some of the land remain reserved as protected conservation land. Thus, of the 114 acres, 88 acres will remain undeveloped land, preserving the landscape many locals have grown to love around this roundabout.
The cache is located at: N42 21.GDB, W071 37.GCF
Each circle, lettered A through I, has its own number value from 1 to 9. No two circles have the same value. The numbers shown in the diagram are the sums of the circles that overlap at those points. For example 12 is the sum of the circles A, E, and F. Find the value of each circle.
