Found a hardcover Lonely Planet Southwest guide this afternoon around 3:15pm in front of the Lensic Performing Arts Center on West San Francisco Street, near the Santa Fe Plaza. It's the 2018 edition, bright orange cover with white title and a slightly worn spine from travel. It's about 7 by 5 inches, and inside there's a red bookmark ribbon and a couple of dog-eared pages marked at Monument Valley and Santa Fe Trail routes. I figured it belonged to someone who loves road trips or hikes, and it would be a bummer to lose it. If you think it's yours, message me and we can arrange a quick pickup.
