My thanks to Trivia Night regular Matt, who sent an email today correcting me on one of the questions from last Tuesday night.
The question was "Which two US presidents were born on July 4th?" The answer as I had it was Ulysses S. Grant and Calvin Coolidge.
Coolidge was correct, but it turns out that Ulysses S. Grant was NOT born on the July 4th, but instead was born on April 27. I had read a site wrong where I got the question from. Actually Grant's grandson was the one born on July 4th, not the former president himself.
The Trivia Maven does screw up on occasion, and does regret the error.
I'll be more careful next time.
