So my buddy got an E-mail yesterday from WDFW saying he had won the Goat Raffle tag.

Says he's got Sept 1 - December 31, any unit with at least 2 tags.
He's asked me to help, but we don't know squat about goats, and even less about what unit(s) we should even look at. Unless driving on 12, 90, or fishing on Lake Chelan counts, we've never even seen the goat units. So were hoping you boys would be so gracious as to provide suggestions on units we should focus on.
A few parameters to maybe keep in mind:
The guys doing this hunt aren't marathon runners, or even backpack hunters.
He'd like to include his father(60+) in this hunt if possible.
He'd like to get a decent Billy.
Pack stock may or may not be an option, likely not.
Vacation timing/length shouldn't be any issue.
He'll be hunting with a rifle.
Thanks in advance!
