I'd love to see mountain bike, cyclocross, and BMX race facilities. Orange County has a huge population of off-road types. I'm not a racer, nor would I probably go watch, but you know it would get a lot of use.
We need to keep an eye on the deal-making. Trust no-one who can profit.
A park this size is going to take time. Wish they'd set a time frame & start moving.
