I've done it several ways. Last year was ideal with the Madden package, but looks like that was one-and-done. It's worth trying out different restaurants/bars that have Sunday Ticket. I've had a few seasons where I could watch in a very comfortable bar usually with sound, but three such places have closed. (Comfort w/ Sunday Ticket is usually a sign of poor business, after all.) One thing that used to work great for me was a high quality antenna I used to pull in a different Fox station in southern VA that often had Panthers games when my local station in Knoxville didn't. Unfortunately, that station stopped showing many panthers games around 2010 (wonder why). But maybe others of you could pull in a few more games a year that way.
This year, I plan to go back to a combination of slingbox streams (which are reliable but choppy) and trips to BWW's (which are extremely noisy). Hopefully, I'll get more than a few games on my local tv or the other Fox from my antenna.
