Casinos don't offer the same proposition bets, which is why there's no single place you can go to get a list of all of them. But there is a trick. Some of the online sites let you see their lines without making you "post up" to bet or even register. Hence, you can see lots of props and where the current numbers stand at those sites. The problem with that is there will be many props at the online books that you won't be able to find when you look for them in Las Vegas. Still, it's a good place to start. Three places that let you view for free are pinnaclesports.com, thegreek.com, and bodoglife.com.
Another trick is to monitor the Las Vegas Review-Journal online, where there've already been stories this week about props available around town. Now, if you combine these two techniques, you'll know what's available in Vegas via the R-J, and have a good idea of how the lines have moved from watching them at the online sites. We know that some of the premium line services also list props and we're told that there's a link to the LVH (formerly LV Hilton) prop list, but we haven't been able to locate it. So for now, this route will yield the best information.
Once you're in Las Vegas, it's fun to walk around and shop for the best lines by checking the boards at several books. This is also important to your result, because not only are the props different from casino to casino, those that are common can vary quite a bit from book to book.
Back to those bets that you can't find in Vegas, the classic is the over/under on the national anthem. If you want a little action before the game (whether you bet it or not), get a watch with a second hand and time the national anthem. They'll be a lot of money on whether Kelly Clarkson goes over or under 1:34. Two years ago Carrie Underwood went over 1:42 and last year a lyrics-challenged Christina Aguilera went over 1:54. It looks like Clarkson will have to speed-sing to avoid another over on the anthem this Sunday.
