The Frost has Come

Last night I went down to the prairies by the Meramec River, just before sundown. The temperature was 50f as the sun was setting. I noticed the deer were not coming down from the ridges to browse as they usually do. The stillness was deafening. By twilight, the temperature dropped like a rock to the upper 30's and the prairies prepared for the coming frost. The rapidity of the temperature drop was amazing. Unless you live in a den underneath the prairie grasses, it would have made for a very chilly evening. The deer are no fools!
