From a road course on the west coast to a narrow super speedway in New Hampshire, the boys of NASCAR expect a tight race this weekend.
"You have to have a good car, you have to get your car working really well, and see what happens, it's definitely a track where tempers can flare a little bit," said Kasey Kahne.
"You've got that bottom lane that's always open. Somebody's always trying to nudge up under you. It's a tough race track, it's a fun race track, but it's a tough race track to get around, run well, and stay out of trouble," said Jeff Burton.
To add a touch of uncertainty to this weekend, NASCAR is throwing in the Cars of Tomorrow.
"Loudon is sort of a one group race track already, and I don't know how it's going to play out with these things, but we'll see," commented Kyle Busch.
To pick your winners, always look for the drivers with the best experience. This week, Martin Truex Jr. and Kevin Harvick embrace the big race at Loudon.
"We like going there, it's a lot of fun for me, I enjoy the flat track still. We're looking forward to going up there," explains Kevin Harvick.
"It's one that I really enjoy. Love going up there and racing on that race track," explained Martin Truex Jr.
With two crew chiefs suspended and a recent trend of surprise winners, keep an eye on the dark horses to motor home early.
