NASCAR: Truck Series Safe: Despite reports from independent blogger Mike Mulhern, NASCAR Vice President of Communications Jim Hunter says emphatically that there is no validity to a story circulating that the Camping World Truck Series will shut down. "There's no truth to it whatsoever," Hunter said. "It's total B.S. The demise of the truck series is the figment of one person's imagination. (Mulhern) has a history of fabricating false stories and this is another example of it. We're very aware that (the Camping World Truck Series) is affected the hardest during this economic recession. We're currently looking at options. We've never given up on a series and we're not going to start now." That said, NASCAR is looking at options to reduce costs such as decreasing the schedule, increasing the number of single-day dates and bringing back the half-time pit stops that could eliminate the traveling crews to five or six members. One possible solution that is off the table is the use of crate engines. NASCAR VP of Competition Robin Pemberton said they are not a viable option because "they're not durable to last much beyond one race" which would raise costs, not lower them. Pemberton feels the sanctioning body has made "good gains with new rules and regulations" and the series "still makes sense."(FoxSports)(6-30-2009) Comment here
