In my travels throughout the biblical world, a few sites have struck me as particularly promising for archaeological excavation.  If bulldozers could remove the modern city of Alexandria (Egypt), I’d guess the entire Roman city would be well preserved beneath.  Next on my list would be Antakya (Turkey), which is built over Antioch on the Orontes.  One of the most impressive sites that doesn’t require relocating a city is Laodicea (Turkey).  Excavations began in 2000 and applications are now being accepted for the summer of 2008.  Laodicea contains monumental remains just under the surface, and it surely would be an exciting experience.  For more information, see http://cognitivearchaeology.spaces.live.com
