mosquito anti-loitering device from Chinatown back in 2010
“Dear PoPville,
There is a constant high pitched alarm sound coming from Georgia Ave and Lamont street. It has been on for over a week at all times and makes it miserable to be outside.
If it is there on purpose as one of those mosquito alarms to wade off the young people who can hear that high pitched tone (like the one at Gallery Place) then I think it’s highly unethical and the city should take it down right away.”
