Love that Gollum!
The problem that I've encountered through all these years are nuts. It seems some people read the books and get so swept up in the fantasy that they think they have to live it. I actually knew of a guy twenty years ago that dressed up like an elf and hiked out into our city park and spent the night out there sleeping on the ground! Then a thunderstorm came up and he was just sitting out in the rain getting poured on! (Thunderstorms in S. Texas can be quite violent!)
This guy also tried to get me into playing D and D and I never could get into it. He loved it, but I found it boring and figured it must be some shortcoming on my part. I often wonder what he would think of me, a dull stay at home mom with two little boys. Last I heard, at almost 40 years of age, he was going around with the Society for Creative Anacronism.
