I grew up on some train wreck that was very pine flavored and scented. I grew up in the Santa Cruz Redwoods (the Forest Moon of Endor was my backyard) and to be honest the wreck it smelled just as "dank" as it did pine. Like if you went for a walk through the forest on a warm day after a rain. It's got that humid, wet wood, kind of funk with a really strong pine smell over the top of it all.
Of all the strains I've smoked, this Train Wreck was the most piney, and I've smoked hundreds of strains from my local shops. The guy I used to get it through moved away and I've never found anything close. If you find a seed, or can get a cut, I'd suggest keeping that baby around for a while.
