I doubt if anything terrible has happened to Buc. He sort of "announced" his departure, in a manner of speaking. I think he may have become a little tired of some of the "bickering" that was going on and taken a leave for awhile.
If, on the other hand, something has happened for the worst to Buc, I know he would want this tremendous forum to "keep a goin'".
I feel confident he will be back at a time of his choosing . . . putting up some awesome posts that make you think.
Cheers to you, Buc, wherever you are sir!
*Edit: Buc - whether we hear from you again or not - you're a DAMN GOOD DAWG!*
