As for me I haven't visited a National Military Park in some years. I certainly have not since US Repersentive Jesse Jackson Jr. had a law passed that directed the National Park Service to interpret that the war was over slavery. Certainly not an objective directive. Althought I am given to understand that this interpretations have been changing in the more recent interpretive programs, I don't know if this is just local to individual parks, or reflects a change in the Department of Interiors "official" policy or not, since these NMP have been experiencing a downturn in attendence over the past few years combine with the effects of the economy.
