The smell of the evergreens on a hot summer morning. Brings back childhood mornings in the Catskills at my grandmother's place...
The smell of honeysuckle here, in June, when it's in full bloom. No bath gel or shampoo they've ever come up with can match the real thing.
The smell of garlic in a meat sauce, as it wafts through the streets. As a kid in the summertime, I had to ride a camp bus through a picturesque Queens neighborhood known as College Point, and in those days, there was an old-fashioned Italian enclave there. The smell of dinner cooking on a late hot summer afternoon could literally drive you through the roof...and knowing that it was at least another forty minutes before the bus dropped me off in front of my door was on the border of unbearable.
The smell of baking bread's great too...
