What do you do with your autumn leaves? And why do you do that?

I’ve been meaning to ask this for weeks now, and just saw a leaf question that triggered this thought for me.

WHAT do you do with the leaves in your yard and why?

Personally, I don’t understand why or where people started to bag ‘em. if you do it, tell us why

I have a great mulcher mower that makes my lawn look freshly vacuumed after I crunch the leaves up. Yum! My lawn is beautifully green and well fed because of this. I leave the leaves in the mulch beds, and if I do have to rake, jus pile the leaves under my hedges.
