Within a days march...

[doug*platypus]

I'd just like to point out, first of all that a day's march for Strider, going about at a great pace on those long shanks of his, covers quite a considerable distance.

Secondly, I'd be interested to find out exactly what would be enough to freeze the heart of our worthy Barliman. It is fortunate that he and Fatty Bolger had not changed places, or the Enemy may have found out much to the detriment of the Fellowship. One of Butterbur's first comments after the nightly visitation in Bree is:

good bolsters ruined and all!

I don't think he would have coped too well with facing down three Nazgul, considering this reaction to the fate of his pillows. I doubt that anybody in Middle-Earth lived more than five minutes' brisk walk away from foes that would freeze Butterbur's heart.
