Burning the midnight tax oil

Thirty-five Colorado post offices will have midnight tax mail pickup for people waiting until the last possible minute to mail their tax returns on Tax Day, Wednesday, the U.S. Postal Service announced.

However, if you still need to buy postage, only the Denver General Mail Facility Post Office, at 53rd and Quebec streets, offers customer service up until midnight. All other facilities will close at their regular time.
