Reno Mayor Roen Cox says the city secretary was driving home this month when she noticed that one of the signs was gone.
Cox told the Fort Worth Star-Telegram that the town has had a lot of lot of thefts and burglaries, and now "someone steals the sign."
Crime Stoppers is offering a reward, based on the value of the sign. Cox says the town will match the reward.
Reno is a community of about 2,700, located 25 miles northwest of Fort Worth.
