Instead of having a hobbit take the ring all the way to Mt. Doom and throw it in, why didn't Gandolph just get on the back of an eagle, fly to Mt. Doom, and throw it in? 1. Gandolph flew on the backs of the eagles a number of times (they rescued him from Isengard, and he flew with them again in rescuing Sam and Frodo from Mt. Doom). 2. the eagles showed in ROTC that they could put up a good fight with the Nasgul. 3. Yes, Frodo made an attempt to give the ring to Gandolph, and Gandolph refused it, but Gandolph wouldn't have had to wear the ring. He could have kept in in that envelope in his pocket until he got to Mt. Doom and dropped the envelope into Doom.
