[Keeper of Dol Guldur]

Seriously, this is easy for me.

Eating bread.

I'm always eating some sort of bread product when I read LOTR. Just plain old sliced bread, out of the package. Bagels, wheat breads, cakes, brownies, any bread group things.

And sometimes cheese. Like, I'll take a brick of cheese and just slice off chunks and eat it as I read, with the bread, or without.

And then every time somebody says something about good bread and good cheese, I'm like "DARN RIGHT!"

Gets me right into the story. I have to read fast too, if I try to analyze as I'm reading, I just don't get sucked into it.

But other than that, my imagination seems to be good enough to keep me in Middle Earth for large periods of time.
