There's a proposal to make a peak season pricing for the top 17 national parks. It would increase the per person daily fee from $10 to $30 and per vehicle daily fee from $25 to $70.

The comment period is open so hopefully people comment, it just seems like those prices will prevent access to what are supposed to be our parks.
