I heard Chris Thile say on last weekend's edition of The Prairie Home Companion that he had just moved to Portland from New York City. Now, I've found confirmation in this article from The Guardian newspaper:
"Thile will tape five or six episodes in the show’s longtime home base –
the Fitzgerald Theater in Saint Paul, Minnesota – and make the rest
around the country, including New York.
For now, he will commute from Portland, Oregon, where he lives with his
wife, actor Claire Coffee, and their 11-month-old son, Calvin."
So, don't be surprised when you bump into Thile at a coffee shop.
