The BMFA have just published new guidance as shown below in red which means public spaces like Girton are no longer available for recreation such as model flying.
Whilst outdoor exercise is still allowed, either alone or with one other person, we are now no longer permitted to leave our homes to visit public outdoor places for the purposes of open air recreation.
Outdoor sportsgrounds or sports facilities (which includes model flying club sites and BMFA Buckminster) have also been added to the list of venues that must close.
