Best spots to watch planes at Denver International Airport.

1
:-)
Planes fly directly overhead!
Hear really cool suction sound behind many planes.
Road paved.
Planes land on both runways, spaced about 2 minutes apart.

:-(
Not as close to end of runway as at old Stapleton.
Cars and trucks whizzing by diminish thrill.
Nobody bothered me in Honda Civic. But in red Ford Mustang, during half hour, 3 people stopped to warn me about a no parking sign.

2
See planes take off about one per minute, but they're pretty high and far.

3
Best overview of entire airport.

Best place to enjoy the roar of the engines as they spin up and go!
