This just came across the radar screen;
Oregon State Park Passes will increase in price as of Jan.1 to $30 for 12 months and $60 for 24 months. Good news is you can buy these passes (good for 2010 or the 10/11 seasons) for the old price of $20 for 12 or $40 for 24 months this month (December 09). Yes, that's a 33% savings!
