There are a few road runners around that still fly under the radar, mainly because the average population in the average room is too young to know who they are, even if they carded them. A lot of them do their best on the rail, making games and sweating them. Then finishing the evening with a strong 1 pocket score against one of the winners or someone else on the rail before moving on. They don't even show up to tournaments, just the action. Next time you're in a room with some fairly serious sweat action, ask the oldest guy you see who's who and he may just point out three or four of the strongest players from the '70s/'80s you've never heard of who are still running.
