Narrative:

Departed apa runway 17L and departed to the southeast and continued to climb to cruising altitude of 9500 ft MSL. I don't recall being released from the apa tower frequency, but I think they did. About 1/2 way through the outer ring of the denver class B airspace, I broke through the floor and continued on to 9500 ft MSL. I did not contact denver departure as I did not realize I had been in their airspace until after I had left it. My transponder was active on 1200.
