UMATILLA — The Grinch is on the loose in Umatilla and is trying to wreak havoc on the holiday season. Find a mugshot of the dastardly character in each of the 12 city-owned parks for a chance to win prizes.

To enter, take a selfie with the mugshot and post it to the city of Umatilla’s Facebook event page (Grinch Parks Scavenger Hunt!) with the hashtag #UmatillaGrinch, or stop by Umatilla City Hall, 700 Sixth St.

A list of Umatilla’s parks can be found at www.umatilla-city.org. Follow the city’s Facebook page for some helpful hints while you hunt down the mean one, Mr. Grinch.
