We all like to grouse, complain, and let everyone know how we'd run things if we were in charge. Fine. When was the last time you actually told the National Park Service what you thought of its plans?

Now's the time, good folks, to clearly express your views on a number of pending issues across the National Park System. You can complain all you want to the Traveler, but we're not the Park Service, certainly not in charge, and don't have the time to relay your thoughts to the agency. So, to help you out, here are some issues that currently have open comment periods:

Higher Park Entrance Fees

This is Interior Secretary Ryan Zinke's idea. In short, he believes that by raising -- more than doubling, in many cases -- entrance fees at 17 national parks during the height of vacation season that that will help reduce the National Park Service's $11 billion+ maintenance backlog. We've outlined the plan, and told you what we think.

There has been congressional pushback, so it's not a done deal. But then, the Interior secretary didn't let some 2.8 million public comments, most in favor of keeping the status quo with national monuments, dissuade him from calling for some monuments to change either in size or allowable uses of them.

The comment period runs through November 23. Go to this site, read all the details, and leave your comments.

Reservations At Arches National Park

There's a trend building in the National Park System: superintendents are beginning to seriously consider reservations for visitors.

With the record visitation numbers of the past two years (307 million in 2015, and more than 330 million in 2016), it's not surprising. Not only are resources getting crushed, but parks don't have the staff to safely deal with these numbers of visitors, and the visitor experience is suffering, too.

Arches officials are just at the very beginning of debating this possibility, and are inviting you to join in the conversation. The plan under consideration proposes a reservation system for entrance during high-visitation season and peak-visitation hours. This system would give visitors certainty of entry, reduce or eliminate long entrance lines, spread visitation more evenly across the day, and improve the visitor experience by ensuring available parking space, a park release said.

Reservations would be required for vehicle entry between 7 a.m. and 6 p.m., seven days a week during high-visitation season (currently March through October, but this may shift as visitation patterns change), and could be made online or by phone.

Comment on this issue is being taken through December 4. You can read up on it here, and comment there as well.

Individul Park Fee Increases

Any more, keeping track of all the proposed fee increases is impossible without a team watching for them. Here are some of the ones still open for comment:

Projects seeking public comment can be too many at times for the Traveler to track, let alone weigh in on. You can do the job without our nudging by bookmarking the Park Service's Planning, Environment & Public Comment website. Check it once a week or so and you'll see which park projects are up for discussion.

Give 'em your two cents. You'll feel better for it, and just might make an impact.
