The historic library will lead kids and adults of all ages on a scavenger hunt through Oregon City with two ways to play. An easy mode will task young kids and families with finding Halloween iteams hidden in the windows of town landmarks like Ermatinger House, Pioneer Center, and City Hall. In the advanced mode, older kids, teens, and adults will tap on a digital badge to read riddles and guess which noteworthy books they're referring to... Answers will be posted at each scavenger hunt stop. Each registered participant will receive a small prize and prize drawing ticket.
