21. I found a site I really liked, but could not subscribe to it because I don't have the capability on my machine to get a podcast. My site was called Dogcast radio! And since I want a dog it would be a neat podcast to listen to. I may try to do it at home on my laptop to see how this works. But at least I seached and read on the podcasts. It is amazing what you can do with these sites and casts and things.
