As far as mass, these pics under rate him i think. It looked like i might be able to fit a finger between the bases on the forehead. The width of the horn at the base was about 1 1/2 of the width the eye. I spent about an hour looking at him in the spotting scope at less than 100 yards. Not sure about a guess on length, not a goat expert, but plenty long for me.
As far as hair, looks like they were all completely shed and even looked like they were starting the fall coat. Long hair is just a bonus - the experience and the chance to nail a big goat is just as fulfilling -heck even what I have done so far can't be bought. It is all we talk about now.
