I mean, in my little part of the world if you go up to any sub 24 year old male and say: " What's the line?" you'll get the betting numbers for the 'largest' local team playing that day.
It's a bit different today in particular though as we're in equinox season (when many major sports leagues play on the same day). So your local college football team is playing today, the world series game 7 is today, and there are NBA and NHL on today, and NFL is tomorrow.
