Harvest Home is an old Pagan tradition, but it's usually celebrated starting on Lughnasa, or August 1. This is a little late to be observing the holiday.
Personally, I don't leave my "Thanks!" -giving for one day a year. I do it all the time whenever I sit down to eat. But hey, a holiday for foodies? 'Tis acceptable
What might be interesting to observe on the day in question, was the Croatan taking in the people of the Lost Roanoake Colony. It probably happened around this time of year and is very in keeping with the holiday's ethic. "Those poor people are starving, they'll never make it through the winter — here, let's take 'em in." That sounds like Thanksgiving to me.
When the pilgrims came over here, they desired peaceful coexistence and that was exactly what happened for awhile. The Croatan event points to that. It wasn't like the pilgrims stormed the beach and came ashore, muskets blazing, sometime back in the 1600s. The situation was screwed up by intolerant, sociopathic dillholes on both sides, like it always is. But let's not go into that here.
I'm one-eighth Iroquois and Shawnee and frankly, I think Thanksgiving is great. A national day of being social. Good idea.
Happy Thanksgiving, everyone!
