Pine trees - that's another one I love. I enjoy going up to Scotland in winter and wandering around amidst the trees up there - the sights and smells make life worth living - and to me that's not an exaggeration.

I was thinking fireworks after greyscar's comments - I agree that the smell of a freshly spent firework is amazing too. Combine the wood burning smell with cooking sizzling sausages and I agree with that one too.

Fresh strawberries are a definite :-)
