There is a significant difference between the smell of a ripe road-kill skunk and fresh skunk spray. Anyone who has had a dog sprayed by a living skunk knows what I mean. In the 1980's I had already marveled at the skunky smell of certain particular strains, and the similarity with ripe road-kill skunk was undeniable. Then my buddy's dog got sprayed by a skunk and we all noted that fresh skunk spray was NOT the smell of that awesome bud we enjoyed. Fresh skunk spray is far more acrid and chemically foul smelling. I would love to smoke some old school skunk bud, but if it smelled like fresh skunk spray I would know that wasn't it.
Same here, Siskiyou. I've said this before in other RKS threads but the roadkill smell we associate with bud is from a dead skunk, not skunk spray. It's a night and day difference. Fresh spray is just a terrible smell. Burnt rubber and sulfur dominate. Roadkill doesn't have nearly as much sulfur in the smell, it almost seems sweeter by comparison. Interesting thing I noticed when my dog got sprayed was that the day or two after it happened the area smelled more like roadkill than the initial spray. Not sure what that means but it was something I noticed.
As for actual RKS bud... I've still never encountered dry flower that actually smells like roadkill skunk. The few times I've actually experienced that smell from bud has only been after smoking it. The smell that lingered in the air was very similar to roadkill. One time the smell was so skunky the chick living on the floor above me came downstairs in a bit of a panic asking me if I could check the basement for a skunk because the hallway reeked. After the initial "wtf?" reaction we figured out she was actually talking about the smell coming from our apartment.
