Thought just now: We haven't had much in the way of mosquitoes, this year. Not if my own experience is anything to go by. I can't remember the last time I got bit.
Seems likely the dry weather has something to do with it. Massachusetts has a drought going on, although I haven't heard the d word used here.
Also noted. Mosquitoes are a more fearful subject than usual this year. They're also part of the ecosystem in a lot of places.
