Signs of spring?. Groundhog Day

Groundhog Day is a North American tradition with roots in the February 2 Candlemas observance practiced by German immigrants. The most well-known Groundhog Day celebration, in Punxsutawney, Pennsylvania, was first promoted by a local newspaper editor in 1886. Thousands of people gather in Punxsutawney each year to witness the groundhog emerge from its burrow, and more importantly, to see if the critter spots its shadow. If it does, winter will go on for six weeks, according to tradition. If it does not, spring-like conditions are said to be coming. Studies have yet to prove any link between the two events, but that hasn’t cast a shadow over this unusual tradition, which remains as popular as ever in the 21st century.
