Yesterday, when I went on-line and looked at Yosemite's famous Christmas Dinner, not only did I find out it started in 1927, I learned that they hold multiple dinners throughout the season and you no longer have to go through a lottery to attend. Its a once in a lifetime thing to do. Put it on your bucket list.
My little book by Washington Irving was published by a respectable publishing house, but it had no date. When I went to Wikiepedia and found out Washington Irving died in 1859, I realized for the first time that the Bracebridge Hall Dinner at Yosemite and the dinner by the same name described by Iriving, were not the same dinner.
