SAN FRANCISCO (KGO) — If you saw someone break out into spontaneous or organized dance Friday, you can thank a San Francisco woman for it.

Six year ago today, Beth Fein took her love for dance to a new level and started what she called the annual Dance Anywhere Day.

She celebrated with friends at Grant and Geary at noon Friday.

Dance Anywhere Day has now gone international, with reports of people as far away as Estonia participating.
