CityShopGirl Citywide Scavenger Hunt!

CityShopGirl is turning 1 in October! And like most birthday parties, fun and games are involved. But this one, a scavenger hunt, involves the entire metro area, a good cause and fantastic prizes. To join the fun, you must 1. Subscribe to CityShopGirl  2. Follow the clues on @cityshopgirl on Twitter and CityShopGirl emails  3. Show up at the cocktail party at Lotus Lounge Oct. 17 when the winners will be announced and the prize, worth over $2,500, awarded. The creative and enterprising team of Bethesda native Kelly Collis Fredrick, publisher of CityShopGirl, and Sarah Damelio of organic skincare company Skincando teamed up to promote local businesses and support Skincando's Operation Sand Flea. MoCo participants include Ginger, Urban Chic, National Jean Company, De La Ines Salon, ILORI, Sweetgreen, Still Point Spa, Red Dog, Crooked Monkey and LA Boxing, plus more from DC. There will be a suggested donation of $5 (and well-deserved) at the party to support Skincando's Operation Sand Flea, which sends burn- and itch-relieving Combat Ready Balm to our troops stationed in Iraq and Afghanistan.  Subscribers can sign up as individuals or a team (up to 4 members) by emailing rsvp@cityshopgirl.com
