Oooh, that smell

If there's one smell that particularly takes me back to childhood, it's the scent of sun-warmed redwood bark.

Schools and playgrounds undertook a change in the '70s from sand to redwood bark - probably a function of post-Prop. 13 costs as well as ease of maintenance. Cats don't use redwood bark as a litterbox, for example. We hated it as kids, because sand was comfy and redwood bark hurt when you fell off the jungle gym. But anyway, that smell instantly evokes my childhood.

So, a poll. Feel free to expand or expound in comments.
