Inyo County Sheriff

I’m a World War II history buff. For my US history class this spring, I wrote about the Japanese Internment camps. I understand that various colleges sometimes sponsor pilgrimages where survivors take interested people to the internment camps. I would like to find out more information about them.
I have only been to one camp – Tule Lake (Modoc County). All I saw there was the barbed wire…something was in the center of the field, but I couldn’t see what it was. I know of Manzanar, in Inyo County, but haven’t seen the site. Any information, particularly partaining to Either Tule Lake or Manzanar, I would greatly appreciate. Thank you very much. Take care.
