Ostrich Weekly Forecast: May 5

Here's something neat: When a farmer waters a field on a sunny day, evaporation cools the air above the field, causing it to sink and spread out at ground level. The surrounding air is forced upward, and, being warmer than the column over the field, rises in an invisible ring. These currents can travel hundreds or thousands of feet upward, and glider pilots, high enough to be mere glints of light from the farmer's perspective, are keenly watching for signs of irrigation, so as to catch the rising thermals, gain altitude and stay aloft. Hawks and vultures are watching, too.

In other words, you never know whose wings you may be lifting as you go about your daily work. Our weatherman predicts week conducive to this type of symbiosis-at-a-distance. You may not see the people whose lives are intertwined with yours, but they're up there, or down there, as it were. If your ship is rising, thank a farmer (and a vegetarian, by extension.) If your plants are thirsty, give 'em a drink, and scan the sky while you do.
