Narrative:

I departed gai on runway 14 to depart the washington dc, ADIZ via westminster. During climb out from left crosswind, the flight instructor flying with me had me make a left turn away from the washington, dc, no-fly zone. The controller said nothing about penetrating the no-fly zone, but I came close (approximately 1 - 1 1/2 mi). The controller could not see my mode C so I returned to the airport. I haven't been flying much lately due to all the airspace changes.
