Thanks for all of the helpful advice.
We ended up booking through Table Mountain Outfitters. I have now read several recommendations for them, and have read quite a few good reviews from bowsite.com and other forums. Lots of groups of 5 and 6 hunters all tagging out in two-three days, good meals, good accommodations, etc. The only negative I have read on them at all is that the owners (not the guides) were a bit too busy with their TV show to give much attention to the hunters, and you only get their film crew's attention if you shoot a Matthews bow. I'm not wanting to be on their show, I just want to shoot a speed goat with my bow, and I would DIY, but I don't have the time to scout my own watering hole out on public ground. This gives dad and I a four day hunt with a reputable company, on pre-scouted watering holes with blinds already set up.
I will post a new thread with the results when I return from the hunt.
