Landscapers have been a problem for me absolutely everywhere I've lived. I have two choices, rid the world of early morning landscapers or sound proof the house, starting with better windows.
I remember a long time ago the town where my dad lived was going to build an animal shelter with an outdoor fenced in area for dogs, which would result in nonstop barking. The neighborhood got together and put a stop to that. Sounds like you would have told them all to just buy better windows and stop being victims.
Do you think that the solution to the stink from the new pig farm next door to you is appropriately handled by you installing year-round filtered air conditioning?
