What do I do about Slugs?

How do I keep them out of my garden in a natural way?

They go an the pavement and at night I can feel them squish under my feet cuz I can't see the buggers.

I don't really care about my plants, it's more for the YUCK factor.
Update: I really do care about my plants but they always die anyway. I have no green thumb.
