I've been doing a lot of indexing of the 1940 US Census. It has has gotten to the point where I've done quite a bit of "traveling" and I wanted to start a list with all the different places I've been while indexing:
Contra Costa County
Los Angeles County
(last updated 13 April 2012)
Not surprisingly, all the states I've worked on thus far are ones of genealogical interest to me. Clearly, California is my main focus and I think it likely that it will stay that way. Ohio and Michigan are two other states I'll work on quite a bit. Since I wasn't able to find many of my Ohio and Michigan relatives, I'm anxious to help get searchable indexes up for those two.
