I FINALLY DID IT!!!!
I ended CoD4 on Vet last night, but the epilogue: Mile High Club, had me on edge til about 9am this morning. I was at the point where I was going to rip my skin off, but I decided to go to sleep and maybe rest would let me finish it. Which it did and now I'm ready for Modern Warfare 2. I wasn't going to get it unless I finished the campaign for the original.
P.S. - For those of you wondering why it took me so long to end it, I just recently got it back from my cousin who borrowed it over 8 months ago(I got the game a year ago) and never brought it back. :-)
- Rock.
