Let’s say you are on an overland trike journey, pitching your tent each evening in the wide open spaces of rural Earth. Of course, being on a trike, you may not happen to have a thermometer by which you can assess the ambient air temperature, and, being one of those astute trikers who always prefers to know local details for your daily journal, you seek another method of determining how hot things are.
Okay, I realize that some of you may well have some high tech solution, like an iPhone 9,000 that displays a readout of weather conditions based upon your precise earthly location using its internal GPS, but there are some of us who yet prefer more primitive methods of relating to the wilds beyond where the sidewalks end.
So, in the purest of purity, with the highest of respects paid to the natural world, here is how I determine the air temperature with no high tech gadgets: In later afternoon or early evening, when I begin to hear the songs of the crickets, I count the number of times one of my cricket friends chirps during a 15 second period. Then, I simply add the number 40 to this number, and, amazingly enough, I now have the temperature without having to pay Apple Computer a single dime! I like the the idea of “free” whenever possible. Try it next time you’re out on the road pitching your tent. These little critters are pretty darn sharp, I’d say!
