Courtesy of the National Park Service, here’s a list of every unit — from nature preserves to historical sites to memorials to seashores — that the Park Service administers.

The National Park Travelers Club has honored 37 people who have been to every single one of them, and 30-year-old Mikah Meyer is trying to replicate the feat right now on a three-year nonstop trip around the country that he started on Friday in the District.

How many have you been to? Take a look at the list below, and let us know in the comments how you’re doing. Here’s a tip: They’re divided into categories, so it may be easier to count up how many you’ve checked off in each section, then add up the total.

You may just find yourself inspired to hit the road.
