Narrative:

On jun/mon/03 at XA30, I departed hummel field (W75), topping, va, in a C172. My intention was to fly for about 1 hour in the local area consisting of the northern neck and middle peninsula of virginia. I did not file a flight plan. 5 mins after takeoff, I changed my mind and decided to go north over the chesapeake bay to check out an area around poplar island and north beach, approximately latitude 38.8 degrees north. My route of flight was north, keeping clear of the patuxent river restr areas, and then northeast to poplar island, altitude was 1500 ft. My sectional chart indicated I would be under the washington class B airspace and in fact could ascend as high as 3500 ft without penetrating the class B airspace. After circling poplar island, I flew west to the town of north beach.
