Has anyone noticed a low humming noise around Sycamore? It has been going on for a few weeks and is especially noticeable at night (when there is less ambient noise) like a low bass subwoofer constantly pulsing? Sounds like the constant drone of machinery or the vibration of a train (but it is definitely not a train) I initially thought it was my refrigerator or a fan, but it is not. I actually went out driving at 4am to try to locate the source (unsuccessfully) with a tool (phone app) to analyze the frequency. It was noticeable as far as 1 mile south of Sycamore (Shuleski Scout Camp) all the way up to 224. Maybe it's just me, but the tool I used said it was around 80 -100 HZ and consistently around 30 decibels. I'd be curious if anyone else has noticed or might know what this is from. Thanks!
