We’re served by 7 telephone exchanges.

The map is the group’s best guess. It's built from reports from the action group members.
Crosses show the exchange buildings. We know these are accurate: they’re from the MK Atlas.

Bradwell Abbey covers a huge area! (Yes, the exchange is in Fishermead!)

The distance from the exchange to the limits at Shenley Lodge, Great Linford, Broughton, Walnut Tree is 4 km.
