Because of XM Radio's well-publicized financial problems, I haven't been surprised to see changes in their radio lineup (wreaking havoc with my preset buttons, but it's not all about me). So it shouldn't have come as a surprise that the traffic and weather channels would change.
But what a change! Looking for the channel with Seattle traffic while stuck in same last night, I found that it now combines Seattle and San Francisco traffic and weather. Well, that would be quite a commute.
Curiosity led me to listen to the other traffic stations and discover additional weird combos:
Atlanta and Miami
Phoenix and San Diego
Chicago and St. Louis
Pittsburgh and Minneapolis
(my favorite) Las Vegas and Detroit
Not to mention the fundamental weirdness of listening to a traffic report for San Francisco while driving in the dark in Seattle.
Yes, I can see that broadcasting the Calendrier Sportif reduces the number of weather and traffic channel space available. Did XM acquire this along with Howard Stern when they combined with Sirius? I hope they received something more useful.
