Ratings being down for the truck race from year to year probably isn't a huge concern to them. They likely look more into how the rating stack up against their regular races. If it's falling behind them they may consider moving it. Having it at terre haute would be cool, 1 major problem would be seating. I believe Eldora seats upwards of 40,000. What does terre haute seat? 5k maximum capacity? Especially if you can't watch from the infield due to pitting. I think it would have to go to a mile. And I think if it did it would basically another pavement race. I personally believe eldora is the prime location for the race. And personally it's the only truck, nationwide, or sprint cup race I watch all year.
