Go to http://www.podomatic.com/search?quer...&commit=search
Click on the link for the one you want to save (not the play button). it will open a new window.
In the menu select download. You will then be asked if you want to open it or save it. Select save. it is an mp3 file so you can put it on your mp3 player or listen to it on your computer at your convenience.
Thanks Adelie -- I will try it.
