Pros:
Fresh air, remote and no waiting. We have a regular group of guys that play two rounds, back-to-back, at least once a week and have been doing it for a few months now. Toney's sounded pretty tempting and was a little over an hour away from Rocklin. (our base course)
This was as far away from flat-land as you could imagine and will test your game as well as your stamina.
We had three guides- Rory, Akasha, Jamie and the two friendly family Pits. You'll definitely need a guide the first time or two around. The guides were great and all three showed great patience for our large group of 10. Rory shot an impressive +1 (I was a 16 =(
Decent Pro-Shop with a 2nd story launching pad, to the 10th fairway, after you purchase a new disc.(I bought a 136gr Bubble Katana)
Cons:
Be prepared to make a day of it. It's 1-1/2 hours from Sacto and a round can easily last more then two hours.
Pack in (and out) what you need. No trash cans on the course. (servicing them would be a bear) There's a garden hose for water at the house. It was pretty good but bring plenty of your own, especially in the middle of summer.
Bad shots can be brutally punishing and you and your friends can spend a lot of time hunting plastic.
Hiking boots are not a must but my feet we're feeling pretty good after the 20 holes.
Other Thoughts:
If you hope to get in two rounds in one day, spending the night would be the best choice, if your not from the area.
As mentioned before, our group always plays at least two rounds in a day. Not this day. We wern't prepared enough but next time we will be. Many of our group enjoyed the course and some had just a down right bad day. We can now say we've played the extreme and there are many other courses we've yet to play . Toney's was an experience none of us will soon forget.
