Guys... you have to be more patient. There is NO snow up there right now. I'm amazed they're even open. Its like the end of the season when they're trying to stretch it out as long as they can, except its the beginning.
At the bottom of central express, the groomed snow is only 6 inches deep in spots, if that. Certainly not enough snow to build even small jumps. They could put up a few rails sure... but with all the rain, they'd just melt and tip over, no point.
And don't worry about any "great weather" today, sure it was sunny in the lowlands, but it was totally socked in with fog (per the usual) and rain/sleeting at the mountain.
Silver Fir is the place to be right now, lots of logs and rocks to jump off of, some pretty huge drops too on the main runs, just have to watch out for holes... I found one today. Lots of fun even in the rain, you just have to find your own fun, forget the park.
