Do you subscribe to satellite radio? Favorite programs?

I got to wondering how many RVers subscribe to satellite radio in rigs or tow vehicles.

I have it in my car and also a portable Sirius boombox that runs on AC power or eight D cell batteries; have to admit I couldn't live without it. Love the weather & traffic, the cable news (CNN, etc.), the classic rock stations, the Road Dog Trucking network and the Radio Classics mystery dramas.

Kinda makes me wonder why there isn't programming specifically for RV folks, too. Are there not enough subscribers in the demographic?

What are your favorite aspects of satellite radio, if you use it.
