Also, I used to do Aeromodelling as a teen, the old school way, balsa wood skeleton covered in tissue, coat it in dope and when dried it was all drum skin tight, good smell too of course. Always fancied doing another ... just for the construction fun of it.
Another one, was an ex of mine, she wore some kinda perfume that smelled like weed/cannabis you some times detect at rock concerts, not condoning the stuff, never done any drugs apart from prescription stuff (beer is my only vice) don't even smoke tobacco, but the smell of the weed or whatever it was does smell good, as did my Ex's perfume based on the same smell.
Another good smell I like is the waft that comes from a Whisky distillery, lots of them around here and there really was nothing nicer than a ride on my Motorcycle in the country roads on a summer day, riding past a distillery and smelling it, don't like the end product though, and as a Scotsman I guess I should !
The smell of good Coffee, goes without saying that is one of the nicest smells too
