Several years ago the old Paul Revere town of Medford (7 miles north of Bean Town 8-) started planting fruitless pear trees in the boarders between sidewalks and roads in replacemnet of troublesome Norway Maples, etc., and at sping time they are in their blossoming glory that is just delightfull.
If your town maintains planting trees similarly, you should encourge them to do likewise! If they want more info they should address the Tree Warden in Medford City Hall, Medford, MA 02155
