023-090709 In the Treasure Corner - The Clue in the Old Book

The Clue in the Old Book!  Sounds like a Nancy Drew title, doesn't it?

Old books and newspapers can be wonderful sources of clues to treasure.  Just this week, this notice appeared in my local paper: 
--------------------------------
Area history
   In 1909, during the hot summer months, camping on the Sangamon River in Mahomet seems to be all the rage.  Last summer, nearly 300 families camped around here, and from present indications there will be twice as many this year.
--------------------------------
Mahomet is a small town ten miles west of here, and there is still a county park along the Sangamon River.  I've detected that park several times, but only in the play areas, never by the river.  You can bet where I'll be hunting next time I'm there!

This podcast discusses reading old books and other publications with the mindset of a treasure hunter.

As always, there's a lot more information in my book.
