I don't find it I the FAA guide to sectionals, there is no stadium nearby, and it's not on the paper sectional.Screenshot_20210823-102415~2.png

the circle is marking out a power plant which you are supposed to not loiter around, notice the "Plant" and the black dot.

I don't think so... It doesn't come up as TFR in the Avare App.

Jeff, Thanks... but it doesn't come up as a tfr when you long press in the center of it...

to the best of my knowledge, the FAA does not necessarily publish a specific TFR for a power plant but they are all covered under NOTAM FDC 6/8818 (not sure if it has been updated with a newer number).  Avare is simply alerting you to the fact that there is a power station there, I'm guessing it is hydro-electric based on its proximity to the water.

The NOTAM for your reference which you should be aware of is:

Jeffrey... I went to Google earth and looked at the "PLANT." Doubt that it's a power plant... In fact I know it to be the Bush Beans plant. It is not even really near the TVA Hydro-electric Dam nearby. The Circle Does NOT show up on my tablet... but does on my phone... Now I'm really baffled.

go to preferences -> Display, the second to last item is "Show Stadiums"  uncheck that if you don't want to see the circles. 

I've been looking through the TFR data download and do not see anything listed for that LAT/LONG (or anything close to it.  I'll see if I can identify where the circle is being drawn from.  Previously the Stadium data was held as a static file but looking at the scripts that generate the download files the file that contains (contained?) the LAT/LONG for the stadiums does not appear to be called any longer.

Maybe they are simply trying to keep the Bush Beans family secret really secret?

Well, here's another...  There might be a stadium in the circle... But the box about staying 2400 ft above points to a smaller magenta circleScreenshot_20210823-162432.png

Um.. this is in simulation mode?

Does it happen in "live" mode? 

Are there, perhaps, simulated TFRs going on, either from your flight simulator if you're using one, or from Avare?
