Looks like the phantom tree decorators got there early this year. The tree is 2 miles north of Sunset Point on I-17 in the middle median.
For those who do not know, this has been happening for the past 20 years or more. Some one goes out in the middle of the night and decorates a tree on the interstate. Usually after Thanksgiving and then it is gone after Jan 1st. Those who do this have never come forward and identified themselves.
