Race fees???

I've been vintage club racing for the last ten plus years and am used to paying $300-$350 for a weekend's worth of racing. I just joined SFR SCCA planning on doing some CF racing with them this season. I went to sign up for a couple races and the prices are $300-$400 for one day events and $450-$600 for two day events. Did the math and actual track time is almost identical. How does this compare to other regions? When I last raced SCCA ten years ago their fees were comparable to vintage events, things sure have changed...
