I have no cable or satellite either, but am blessed to have a client/friend who doesn't mind me using their login credentials. It was more recently that I realized I could use them to watch things other than ESPN3, as in the Presidential debates.
Sling tv, I am not familiar with. I am a HUGE fan of Slingblade, though. Possibly my favorite movie of all time.
Your post has inspired me to start a thread of my own, where bonus coverage of the tv coverage will be included.
