Where have we been?

When I mention National Parks as a hobby the first question I usually get is "How many have you been to?" Well I wasn't sure, and as you will see in a minute I am still not totally sure. Part of the reason is that the NPS is peculiar in how they list the properties they administrate, part is because there are a lot of affiliated parks that get some funding from the NPS but are not in the NPS, and lastly there are many NPS trails that are not counted as parks. All that said and after consulting the ever-knowing Wikipedia, I calculate we have visited 60 of the 394 National Parks Units.
