Finding the balance between preservation and development is a tough order. On one hand, once historic land and structures are developed they are gone forever. On the other, communities must have a tax base to thrive and prosper. We all have a right to live in the present. It is a mixed blessing, but the economic and housing crises have been playing a role in the preservation of Civil War battlefields. A slower market means fewer buyers and lower property values, which in turn means owners are more willing to sell to preservationists. This has been especially true at Gettysburg.
