Trees come mainly in WHAT material, Andria? The answer to my question should clear up your confusion.
As for your 2nd question, yes, that is indeed be Roland Deschain. Are you a fan?
*Snicker*
I am such a slavering fan that I hope they never do make that movie, because no one they cast as Roland would be good enough, IMO, unless they managed to get Daniel Craig to play him; he has the most perfect face (homely) and eyes (1000-yard stare, "bombadier eyes") to play Roland, I can't believe I'm the only one who's thought of him. Also I thought he acquitted himself well in the rather-ridiculous "Cowboys and Aliens". I'm a massive King fan anyway, but that is his Magnum Opus. Have you read 11/22/63? At one point there is a mention of FBI agents taking a great interest in Oswald, pre-11/22/63, and one of the agents mentioned is named "Fain".. either Richard or Robert, I can't quite remember the first name... but I'm pretty sure he's referring to Flagg, the "Walkin' Dude".... my son is out of state right now so it's hard to have a book discussion with him, but I think he would probably concur... I think the destruction that the protagonist is creating in 11/22/63 by changing the past is analogous to those "places between", the "todash" journeys, and I think this guy Flagg/Fain/Walkin' Dude has used that temporal anomaly to weasel around in time... Just my opinion, of course... Just recently I *finally* got
thru the waiting list at my library to get "Dr Sleep".... yet another excellent read from Mr. King...
