Montgomery County, Maryland - between Baltimore and Washington DC. It's a major high altitude thoroughfare for all East Coast commercial flights. The Washington DC flight restrictions create a bottleneck so that commercial flights have to make a wide turn. On a clear day I can see 4 planes every 5 minutes, with perhaps a dozen parallel and cross-hatched contrails.
PS these are not the black helicopters - they prefer to fly at about 500 feet over my house. What a racket!
