Associated Press reports higher fees for Arizona state parks starting in March 2010:
The [state parks] board agreed earlier this month to keep a premium annual pass, which allows full access on weekends at river parks. However, the fee for that pass will increase from $125 to $200 [an increase of 60 percent]. The cost of Arizona’s standard annual entrance pass will go up from $50 to $75 [an increase of 50 percent].
Park fees may soon rise in California, too.
