Hiya Guys,
Interesting tread you got going here. I I have also spent countless hours through the years at the Library scanning old newspapers from around the turn of the century on microfiche and now days, the computer.
I look for picnic, festival or any type of meeting notices inviting the public to various outdoor events.
In the days before radio & TV, socializing was the main form of entertainment. People looked forward to Sunday (or any) activities that got them off of the farm for a while. I Look for ads like:
"Odd-fellows picnic July 2 at Wagner's Grove 1pm - bring a dish, Fun and games for all"
I jot this info down or make a copy of the print if available. Then continue reading the paper searching for more clues and/or leads. Once I have several leads I'll go to the librarian and ask for a Plat map from the same time period. Find the land owned by the "Wagner" family. Now I know when and where a picnic was held. Check earlier and/or later issues, it's possible it was an annual event, which means possibly more goodies! Further research on the "Odd-fellows" may produce further clues or leads.
(Obviously, do I really need to say this ... "Odd-fellows & Wagner were EXAMPLES")
I have found many, many places to hunt using this method. Including a 1874 train wreck that was close by. A little leg work can tell you if the place is hunt-able. I go to the property and just look for a good place to picnic. It may be built up by now, OR it may still be pristine virgin ground. Now days with Google Earth you can zoom right in to the area in question and find out SO much more before you even leave the library.
Also on the subject of Libraries and librarians ... I have also gotten a tremendous amount of help and additional leads from them, they know all kinds of things you may never even realize. Think about it, librarians probably lead a dull thankless life for the most part. If you take one into your confidence tell her you are “Researching TREASURE leads” and explain why you need her help. Believe me you will spark a bit of adventure into this women's humdrum life that she's gonna love. They will bend over backwards to help you out. I have had a couple of old cronies in the past, but most times they are a big help. I have returned on a couple of occasions and rewarded them with a silver coin or interesting relic to thank them for their help. Try it. It works!
