Picnic
The Buenie Picnic has been held since 1929, on the Sunday of Labor Day weekend, as a benefit by the local Immaculate Conception Catholic Church. In 1971 the picnic was raided and parish priest Rev. Carl Ruhland was charged with "running a gambling house". He was fined $100. Following that incident, in 1973, the Iowa Legislature legalized bingo, raffles and other low-stakes games of chance.[5]

According to the residents there were some old family cemeteries in N. Buena Vista, but supposedly the graves were moved to Immaculate Conception Cemetery years ago. Buenie residents also said; some old cemetery records of the past were lost during a terrible fire at the first church in N. Buena Vista Iowa. I could not find the date of the fire.
