Preparing to leave home to research

Anytime you're leaving on a genealogy trip, you should prepare yourself as much as possible so that you can dedicate your time for that elusive ancestor you're searching for. In my case, I get my research plan together, all paperwork (or computer files) and anything else that will help me. One of those things is my prepared census research form. My census search form has space for each census year and as much of the information that I can write on there regarding the years married, number of children, immigration year, etc. Did you know that the 1900 census indicates the person's month and year of birth whereas the 1850-1880 and the 1910-1940 censuses indicate the person's age?
