How come nobody tells us about these things and we have to discover them by accident?

Case in point:  this Sunday, the Altadena Music & Arts Festival will take place at Loma Alta Park from 10 AM-3 PM.  Performers include Sligo Rags, Pirates of the Black Swan, Lance Anderson, Leslie Perry,  Bill Burnett, and many others.  

As well, the Naked Crow Mountain Bike Challenge will take place that day, a fine festival for elite mountain bikers.  SIgn-in starts at 6 AM, race starts at 8 AM, again at Loma Alta Park.
