I think there are," things afoot", ie, as was mentioned a right turn filter.
And I agree with the 60,000 seater stadium post, personal opinion is
the statium should be out of the residential areas.
Were I live, It is a cul-de-sac only 8 houses, but 3 rather large Sycamor
trees and when in leaf my living room is like the black hole of Calcuta, to add
insult to injury, I also have a 50Ft Sycamor in the side garden, so before the
Green bins, in the Autumn, side garden about 30 bags of leaves and weeks
getting rid of the seeds, plus getting gutters cleared out.
I still like trees though :-)
