----------------------------Original message---------------------------- Hi Cindi-- The National Ocean Service may be a lead, if an aerial photo will do. They have 890 of the largest airfields in the U.S., usually at a scale of approximately 1:30,000. If an orthophotoquad will suit, try the nearest ESIC or USGS office.
