It’s evening, and the sun is going down; whether you’re in the Deschutes River valley or up in the Cascades near Salmon La Sac, you will hear the chirps of crickets. If it is in the high desert near the Deschutes the beautiful chirping that you will hear will probably be made by true crickets -- field crickets to be precise. If you are not in the high desert, but up in the forested mountains of the Cascades, it will be a whole different picture. Instead of the lovely serenade of the field crickets that could lull anyone to sleep, a loud, obnoxious screech meets your ears. Eeeeeeeeeeee!
