Reader: In Search of a Natural Christmas Tree

A reader writes:

We live on 14th and Wabash and we are going to buy our tree tomorrow. Do you know where can we buy a natural tree this year? We were sad to see that Bob's is no longer in Printer's Row.

I hope you know other options like a local church or something. Thank you!

It's been a couple of years since Bob's closed down and frankly we haven't seen many spots pop-up since.  Any readers have any insights?
