Some cheer to start this month and to see that May Day isn't just military parades... Beltane, the Gaelic name for the month of May, begins the season of Light in one Celtic calendar. Celebrating light and growth has been seen as human necessity as has been continued through human history.
Wikipedia has intriguing directions of study upon this subject, just look up Beltane and click the links provided in the article.
In elementary school we'd play 'ring around the rosey'(from another historical holiday but we didn't know that)and would have crowns of flowers. One year we did have a Maypole!
My father used to make me dandelion crowns. One type of crabgrass here grows very tall (as shown in the post the other day), making for wonderful whistles. Sometimes my father, grandfather and I would sit on a bank, whistling away as a 'crabgrass band' while my mother would smile but think that activity was not a ladylike divergence. For me, it was worth 10,000 scratchy, lacy pink crinolines. A Victorian lady I am not.
