If you find yourself walking the streets anywhere in Sonoma County this week, keep your eyes open, or you might miss the art. For the first 10 days in April, Pie Eyed Studio is hosting the second annual Big Art Treasure Hunt, boasting 50 pieces of original art hidden throughout the area. The rule is: if you find it, you keep it, meaning that this hunt is the perfect time to bolster your collection. Pie Eyed will be releasing cryptic clues on its Facebook page between April 1 and April 9, and the studio wraps up the hunt with a party on Sunday, April 10, at 2371 Gravenstein Hwy. S., Sebastopol. Noon. Free. 707.477.9442. facebook.com/pieeyedstudio.
