Finishing up off campus...

[twocosmicfish]

How amenable is the archaeology field to doing your research and dissertation off campus, and can anyone speak from personal experience? Due to my work requirements, my wife would have 3-4 years to start her doctorate on campus, but we would then relocate elsewhere - conveniently near the geographic area of her intended research. Understanding that it may take an additional 3-5 years to finish her thesis, has anyone seen problems with doing the remainder of her work off campus? I am not asking about school regulations - I am asking about personal opinions of practicality, difficulties to expect, etc.
