Summary:
More stuff being built. I think there are a couple of Whistler-style drop ramps being built (The builder actually did not model them after Whistler). A few more jumps have been built and another course has been started at the top of the hill.

If you really want, you can hit up the Antioch Skate park right near Prewett Water Park. I hardly ever see any cops there. Weekends it can get crowded. It's supposed to be boards and blades only. No scooters or bikes, so leave the Razor at home, kiddies. Pretty decent flow. Fun lil pool. Definately bring the Hardtail if you go to the skatepark. Right across the street is Deer Valley High. It has a bunch of ledges and stairs. The catch is the school gate get locked up on the weekends. Be sure to check if the grounds keepers forget to lock up! Check out Black Diamond Mines at the southend of Sommersville Rd for XC fireroads.

Summary:
Sand Hill is an awesome place for beginners up to pro level riders just looking to have fun. The DS course is great as well as the mountain cross course. The mountain cross has ginormous doubles and banked turns and the DS course has great banked turns. The downhill course is verry short because it is placed on a hill. Not too much fun, but it was okay. The dirt jumps are great especially the car jump, but watch out for the truck jump, the lip kicks you forward and it flipped my friend onto his face. Otherwise I had an absolutely awesome time and if you are in the area then deffinitely take a peak at Sand Hill Ranch.

Recommended Route:
The MTBR directions are fine.

Summary:
the BMX track is sick has really nice doubles. The owner was nice and let us on the sloam track with our BMX bikes. But themotocross side for dirtbikes is a rip off now. It is 20.00 per ditbike, 25.00 per qud, and they charge for spectators. you might as well go to CARNEGIE.
