Airspace Boundaries
Let's say you are flying through Avalon airspace at 2500ft. Those familiar with the aerodrome would know the AV CTR is class D from the surface to 2500ft. From 2500ft to 4500ft you are in Class E airspace. If you intend to fly at 2500 ft in the AV area as a VFR aircraft will you be in class D or E airspace.
