Here is some budget trivia and probably way too much information. No politics, just facts.
2013 NPS Budget (Greenbook)
http://www.nps.gov/aboutus/upload/FY13_ ... enbook.pdf
The total budget for the NPS is about $3 billion.
From this data I extracted spreadsheets for:
1) the budgets per property (park, historic site, monument, recreation area etc)
2) the visitation per property.
There was missing data for a few but I ended up with complete data for 313 properties (budget & visitation). The budget is for 2013 but the visitation is for 2010. I also have the acreages for 2011 if you're interested.
These are the top 20 subsidy costs per person: (i.e. Budget / Visitors)

It would be nice to be able to calculate cost per person-day. For example the $10 per person for Yellowstone might be for only an 8 to 12 hour average stay = $20 to $30 per person-day. While ISRO's $280 per person might then be closer to $70 per person-day.
