1872, Wenonah's first 4th of July
Here's the program for Wenonah's very first July 4th celebration. It's from 1872, the same year the Wenonah House was opened and the year before Wenonah was incorporated. In 1872, there were 10 houses in Wenonah and during the summer season, the 40-room Wenonah House was fully booked. Two more items that you may find interesting: the celebration started at 5:00 AM and ended at 11:30 PM --- a full 18 1/2 hours; and dinner and supper could be purchased from the Wenonah House for 75 cents and 50 cents, respectively.
Can't find any photos of the Wenonah balloon ascension(s) but I found a photo from an upstate NY county fair balloon ascension and an account of a balloon trip from Buffalo, New York to Salem, New Jersey -- which took place overnight on the 4th of July, 1874.
