I live about 20 miles from Houston Raceway Park and when the wind was right, I could faintly hear the Top Fuel cars running. Could also hear the noon time and the 4 o'clock whistle at the refinery when the wind was right when I was off. They were about 8 miles away as the crow flies.
Something local here that's pretty cool. Dubbed as "Loudest Concert in the World'. I could actually hear it from my house about 10 miles away last night. Wasn't real clear and the slightest noise around me made it impossible to actually tell what song they were playing. Too cold to stand outside anyway.... I just thought it was cool to be able to hear it.
