The Top Kicks Military museum is located just to the West of Petersburg. The museum was started as a hobby by a collector of military items and is located next to his home. This museum was founded to preserve and restore military equipment for display. The exhibits include Jeeps, trucks, ambulances, tracked vehicles, weapons, field gear, mess gear, rations, radios and uniforms from World War I to Iraq. The museum attempts to educate their visitors to the experience of the U.S. armed forces. The vehicles on display were restored by the museum to their original or near original state. Other items displayed are antique items such as candies, cigarettes and various sundries which were in the posession of members of the armed forces.
