1.  In Ancestry I searched by my married name and I got information about where I lived but did not get my birth certificate or yearbook.  I then did a search by my maiden name and changed my location, the very first entry was my birth certificate and then my marriage license. 
2.  I searched for my grandfather and I was not sure of his exact birthdate, so I took a stab at it.  I found his marriage certificate to my grandmother.  It was interesting because her name was spelled differently than I had seen it spelled.  Both the first and maiden name were spelled wrong according to what I have seen before.  I am not sure if my grandmother changed the spelling.  I will ask my mom if she knows.  I changed the birthdate and then I found a census where my grandfather was 16.  Seeing the original document was very interesting.  It says that he was born in Ireland.  It also says that his parents were born in Ireland and that jives with what I have been told.  I was always told that he was born in Minnesota, but I went looking for his birth certificate and could not find one.  When I have more time I will get more info from Mom and see if she knows for sure where Grandpa Pete was born.  I found his draft card.  There I found where he was born and exact birthdate.  He was born in the US as I suspected.  I will go further into this at a later time.  I know that he did not get drafted because he was already 28 and his parents were his dependents.  He was single at this time.
3.  I may have done something wrong but when I went looking for pictures by searching South Dakota I received a message that said the there were no pictures collections that were unique to South Dakota so I clicked on related pictures.  There I found a picture of a baseball player who once lived in South Dakota.  I then did a search and put SD in quotation marks.  I found a poster that dated to 1890 where cheap land was being advertised for sale.  It was found in the LOC location.
4.  I looked up the town that I had lived in for 37 years until I moved a year ago.  I found an old book on the early history of that county.  It was easy to find where it mentioned that particular town in the book by hitting the HIT arrow.  I note names of people that were there when I first came to town.  Interesting
5.  I chose Hill City, SD.  I don't know everything about it but I am learning.  I chose the 1903 map.  Two buildings on main street are still there.  One was the Community Center which today would be the Black Hills Institute, but this does not jive with the information given by the locals who say that this building was built by the WPA.  There is a plaque by the building that has a number on it that verifies it as a WPA built.  Maybe the building was rebuilt.  The other building was called the Harney Peak Hotel.  It is located exactly where the Alpine Inn is located today.  It seems to be the same size and looks very similar to what is there today.  It would be interesting to see if these were the exact same buildings by doing more research.
