Which state's transportation department posts drawings of llamas on its social media?

The Washington State Department of Transportation (WSDOT) posted a quick drawing by an employee of a llama on the freeway in response to a real-life incident in which a llama was on the freeway.

The image was retweeted 65 times and favorited 123 times within a few hours.

When the same image was shared on social news website Reddit, an impromptu question-and-answer session began between WSDOT and the site's users.
 
"I'm impressed. Used to live in Florida and North Carolina and have never seen such things from a government organization on social media. Keep up the good work. Seriously, no sarcasm. FLDOT is years behind," Reddit user windedsloth wrote.
