interesting, Sally & I like watching TV programs on Bigfoot, were not believers or deniers, but I find it interesting. I do not have any explanation what happen or what we've experienced twice, Sally & I were camping in the Ozarks this was 3 years apart in time in the same spot that was off a secondary National Forest Road about 18 miles in. We were @ the bottom of a deep holler with a connecting hogsback ridge. Great camp spot with a creek running near by, withthinned grove of southern pines, hardwoods around camp with heavy thick woods. The area were we camp @ was logged off years back (thinned out). What was odd both times was Sally & I went up the dirt road for a walk with our dog Sadie Girl & one thing we've notice during the day light time was NOT one bird, frog, or any animal noises @ camp or on the walk, NOT one animal track on the dirt road & we walk about 3 1\2 miles up & 3 1\2 miles back listening & looking, the only tracks were ours when we were coming back. In the evening I built a fire, Sally made supper & after supper we had a few adult beverages listen to the crackle of the fire & making small talk we both noticed that zero frogs noise by the creek, no sound of Southern Cicada's, no fire flies, no whippoorwill's, no coyotes howling & etc. This was in the 3rd week of May both times. It gave Sally & I that eerie feeling but we went back a second time to see if it was just a one time is a coincidence, it was the exact same thing what I mention no sounds of animals or insects. Like I said we ain't saying it is Bigfoot or some cryptic creature ET thing was the cause of this, we just find it really odd what we experienced twice. The funny thing is we've camp all over that one particular Rangers District for many years traveled all the main, secondary dirt roads, trails, logged off tracks & always hear animals noises during the day light hours & through out the night.
