When the lawn police were last here, after my son had trimmed
everything in our yard to six feet in height, I pointed out the
neighbor-complainants hedge behind their patio which reached the
patio roof to give them privacy from their neighbors´ pool.
Although it seemed to catch the lawn police off guard... long pause..
there was no indication of any shame.
[The straightline arrows indicate the location of each
´offending´ hedge.]

Our filbert trees that were part of the hedge have not shown any signs
of coming back, neither male nor female ones..
