Annually, in October, volunteers get together and dress and act like Civil War soldiers. They relive the Battle of Cedar Creek with canons and rifles and horses and wagons, columns of men trooping through the fields and backroads of the area. They try to be as realistic as possible (given the change of the property in the last 150 years) and get permission from the present land owners to "trespass" through their property.
The re-enactments are done over a two day period. They have encampments and drills.
See the website for the time and place for each battle.
To get upclose vantage views of the action, you can buy a two-day-pass ($15). It doesn't cost you anything to just go and see the encampments, but the re-enactments are on private property and having the pass is less of a problem than trying to see the battles without it.
