Don't forget the ruts! Loretta's has 42 bikes on a gate and 20 gates a day. Not only do the braking bumps get pro style but there are also 15 ruts wide going through them.
As with most tracks, for the intermediate and above rider it's not the jumps that separate you, it's the turns.
I think Broc's a great guy and you definitely have a beautiful private track... I believe for training you need more turns, more rollers, more mogul type bumps, more ruts, and whatever nasty abusive obstacles you can think of. Not just sprinkled throughout the track but the whole track needs to be abusive, then just a couple jumps mixed in to catch your breath.
If you want a great example check out Jimmy Weinert's turn track. I don't know if there are any pics or vid on the web of it (maybe just the main track) but it's 2min 30 secs lap times of pure abusiveness. I would recommend to anybody wanting to go to Loretta's to make a point to go to JWTF when you think you are ready and try to put down 25 minuets on his turn track at 100% max effort. If you can get 20 minuets without loosing more than a second or two per lap, you are ready.
Just noticed, you went last year, you know what you need. Good luck!
