Narrative:

Transition through patrick air space at 500 ft. Tower cleared me to the north. Climbed to 1500 ft. Did 2 rolls and 1 hammer head. Heard radio call from other aircraft about biplane doing aerobatics in patrick's air space. I thought it was me so I dropped to 900 ft (over water) exited to north heard patrick way 'biplane at 4.5 DME.' here is the problem. If the tower clears you to the north, is that 5 mi and can you now do aerobatics. If not why would they clear you.
