Pros:
Uniquely challenging. The drives on baskets 3 & 4 made my heart freeze for a few moments after release going over water. Given the space available, it's quite amazing that course builders fit a legit 18 in. Some really nice variety of tee shots with varying wind conditions. Hippy Golf is alive and well in the Hippy capital of the world!
Cons:
The teeshot for #10 is seriously intimidating. Must carry the water into a very strong headwind.
Other Thoughts:
I've lived in the East Bay most my life, and have driven by "that long looking lake" countless times on Hwy80. I even have customers very nearby in Berkeley, and today was the first time I ever set foot on this land! Thank you Disc Golf! "Margarito" is currently the local source for selling previously lost discs for $5 bucks each. He had about 15-20 on him with at least half being Stars or Champs. Local guy I played the last 7 baskets with mentioned that park maintenence recently cut down all the bushes and overgrowth just below the train tracks, where homosexuals previously would be "hanging out". So, my experience was quite pleasant without any of the shannanigans mentioned in older posts. Yes, many joggers and bicyclists, but nothing to complain about. I chucked a roller into the lake on the approach shot to 18, but waited about 20 minutes until it finally came back to shore. I highly recommend playing with floatable discs (Wahoo, Dragon, & Hydra was my set up for the day).
