Airport; Human Factors
Checked NOTAMs for DTL; read there was PJE (Parachute Jumping Exercise) within 3 mile radius of airport. Took runway intersection and took off. Upon return to the airport I saw there were yellow 'Xs' put over numbers of the airport. I was unable to see them when I took off due to the intersection takeoff. I thought that they had something to do with the PJEs since there was nothing about the runaways being closed in the NOTAMs.
PA-28 pilot reports departing DTL from a runway intersection; with only Parachute Jumping Exercise (PJE) as an airport NOTAM. Upon return to the airport; yellow Xs are noted over the runway numbers.
