Head out for a drive in the country today. When you hit that spot in the road where the dead skunk carcass is and it reeks like a muthafucker... you have found the trait you (and everyone else) are searching for in "old school skunk".
Dunno how it shook out in other parts of the country...but "skunk" here in the Rockies made a stand in the mid-80's...and by the 90's...there was no "roadkill skunk" to be had anywhere whatsoever...just the crap the Dutch left us from the beans they recieved and "reworked" that is sweet and common....and not really SKUNKY at all anymore....
if you find it you will be everyone's best friend...including mine. LOL.
good luck!
