In recognition of Thanksgiving—and the short holiday week that generated very little in the way of subway news)—I’ve decided to do a special holiday edition of Signal Problems featuring something I am very, very thankful for: dogs in bags. So let’s celebrate and give thanks to the one thing that makes any subway ride a good ride.

MTA Rules of Conduct Section 1050.9 Subsection (h) Paragraph 2: no person may bring any animal on or into any conveyance or facility unless enclosed in a container and carried in a manner which would not annoy other passengers.
