Mark, if you mean by 'best' as in the best for a book goat, you are in the right unit. IF you mean 'best' as in lots of goats that you'll be hard pressed to choose between, there are some others. I take from your handle that you are a non-res?
You'd be surprised how much help you might get should you draw. I know lots of folks on this site that would be willing to help you, me included. I admit I do not know the San Rafael for goats; sheep, yes, goats no. But I believe the last record was taken from there.
You might try Rusty Hall of Trophy Hunter Magazine, he knows the records and where they come from, I'm sure he also would know a guide.
I'm sending you an e-mail....ok, it's a tease-mail of some Utah goats.
