I was looking through a new mag (Dirt Rider or Rev!, cant remember for sure) and I saw an ad for Camelbak that said "Internal Combustion Good, Spontaneous Combustion Bad" and it had a picture of a guy on a bike. Last I had heard there status as Dirt friendly was questionable, anybody know anything? Seems to me the greenies would be kind of mad if someone that supports them has an ad that says "internal combustion good" :think:
