The interior of a Pratt & Whitney F100 jet engine in an USAF F-15 looking forward from the thrust nozzle.

In Dallas, US 75 is known as North Central Expressway. This highway goes all the way from (unsigned) I-345 in Dallas to the border with Manitoba, where it becomes Provincial Highway 75. This is a 30-second exposure taken while driving south on North Central Expressway.
