Thinking about the larger picture, it is fascinating to me that the canoe craze of the 1900-1930--with canopies--addresses some needs that we take for granted. What would you do if you lived in a hot, sweltering apartment in a big city such as Boston if you are tired of going to the cinema? The best air conditioning is on a placid lake or on the Charles River. But, the mosquitoes!
Today, we turn on the air conditioning in our apartments, homes, and cars. If we do step outside and face the mosquitoes, we spray ourselves with Off! bug spray, lather our skin with DEET, or turn on an electronic device which makes sounds which are repellant to mosquitoes. At least such repellants are a bit more pleasant than the "6-12" bug repellant of my youth!
