Other - Transporting Mushrooms on an Airplane

[Jester]

Hello everyone. I have a hypothetical question to ask you all. Assuming, hypothetically, that I have a friend that is planning on coming out to visit me and wants to bring 1/2 of shrooms with him, but he lives far enough away thathe needs to fly rather than drive, what would be the best way, in this hypothetical scenario, for him to bring them without dealing with mailing or shipping them. (note: it's hypothetically a domestic flight, so there would be no going through customs or any of that).
