Today we mark Columbus Day, which is a national holiday here among other places. It officially celebrates the anniversary of Christopher Columbus's arrival in the Americas on October 12, 1492.
Though I'm sure there are significant observances elsewhere, it has been my experience that the day is primarily one for retail sales events more than anything else.
I suppose there is a precedent somewhere given the protesters of the day and their counter celebrations such as "Indigenous Peoples' Day" or "Native American Day". It would seem that more governors are of the Jerry Brown full of crap variety with their 'state holiday cancellations' of Columbus Day.
Anyway, Happy Columbus Day if you are of the persuasion. If you are opposed to the notion, I hope whatever substitute your feeble mind came up with as a replacement floats your boat.
