What Podcasts do you listen to when you travel?

I am currently 34,000 feet in the air (on my way to LA) and I was wondering what podcasts you guys listen to when you are traveling. I tend to download podcasts that I generally do not listen to. I also try to listen to newly discovered shows when I am traveling.

Do you listening habits change when you are traveling?

At home I have about 8 podcasts I listen to regularly but when I travel I have around 14 different podcasts.

Here is whats on my List right now.

1. Stuff they don't want you to know
2.The Steve Austin Show
3.Mysterious Universe
4.Joe Rogan Experience
5. Wrestling Observer
6. Skeptoid

Usually I have a backlog anyway and get to catch up but I also try and load up on Hardcore History shows that I've missed.
