As the cost of these local National Forest passes continues to spiral, it may be a good idea to remind people that you can buy an "umbrella pass" which will cover ALL the National Forests, National Parks, National Monuments, etc.
Keep in mind that EACH National Forest may change for recreation, and there are currently dozens (scores?) of NF jurisdictions which charge. Your White Mountain Pass will be of no value in another jurisdiction.
If you recreate only in the WMNF, then their pass is the best value. However, if your annual plans include hiking elsewhere in the US as well, it might be a good idea to investigate what is now called the "America the Beautiful" pass for $80. (This is same pass available to those 62 and older for a one-time fee of $10.)
