Satellite Radio

OK, I don't even know what satellite radio really is. I am assuming that it allows you to recieve signals that are not normally broadcast (stations in between stations??) Obviously, if i don't know what it is, I don't have a need for it at this time. I enjoy my regular radio stations, and I also enjoy finding stations that I don't normally listen to. An example of this happened on Sunday night when I to0k my son back to school at Eastern Michigan. Although I had listened to the weather, and I knew that it could rain in the early evening, they did not say it was going to snow until much later. (so much for dopler and all of the other technology weather forcasters have at their disposal....ever notice that the more technology they have, the more wrong they are in their predicting??? Another example of technology that doesn't really help us too much!!) We left the house at 5pm, and it began snowing about 15 minutes into the 45 minute trip to Ypsilanti. It snowed the entire time I was at EMU (about 1/2 hour) and the entire trip home (which took nearly 90 minutes). I could not get my regular radio station to come in, and I needed to know about the road conditions / accidents / weather. I found a really good station that was out of Ann Arbor that gave me updates every 10-15 minutes the entire evening, and had a combination of country and classic rock inbetween to calm my nerves. I now know that there is a station I like when I am in that area, and my son also enjoyed listening to this station. I think in this area, this market, there are plenty of stations to listen to and find information, at least for me and my purposes. I guess that if I listened to a particular kind of music that was hard o find I may need other stations or options (put in a CD??!!). i guess that I just don't understand it all, and the purpose for it. It seems to me to be just another technology "thing" and we as a society are obsessed with having the latest "thing".
