Well in my opinion it is just trying to link to totally unrelated things.
It was found that at a certain altitude it is possible to tell the temperature by counting the amount of cricket chirps in a minute and then putting that number into an equation. Works real well at a certain altitude, but when it was attempted at significantly different altitudes it was found to be incorrect.
My only point is that we all know the summer sucks for the markets, so I could say, well when my grass dries up and turns brown the markets are gonna do bad. Whenever summertime comes around I'll probably be correct.
