If Mike has a tree that grows in front of it, or experiences heavy weather conditions, he may have issues. Then there's over the air high def, which he could get just with an antenna. He can get uncompressed HD signals that are gorgeous, if he's within line of site to the broadcast tower. So ideally, he could cut the cable entirely and then just stream shows off the internet that he doesn't get live.
