I have a shirt that says "Not all who wander are lost" on it, and it has drawn comments from about three people, total, and I've had it for at least that many years. Granted, the quote also isn't exact, but it's a great way of at least telling if a fan is literate by if they see the shirt and say "Oh! Sweet! Lord of the Rings!"

Going somewhere in costume, especially wearing the leaf brooch is a great way of meeting people who love LOTR.

If you're really trying to meet people who like LOTR, the one place I can think of to go to that has more LOTR fans than anywhere else (short of a LOTR exhibit) is a renaissance faire. I go to one every summer, and ever since I added the leaf of lorien to my costume, I get lots of comments on it. Everyone's already geeky at a renaissance faire, and everyone's obsessed with the midieval/renaissance. So there you have it: a perfect meeting ground.
