Park policy allows racism

Tax-paying foreigners not entitled to local price at National Parks

I really don't have any objections to the policy, but it allows racism

First hand experience:  I was with a group of Asian Americans of different Asian backgrounds, all US citizens. 

I was the only caucasian in the group.  I was the only one having to pay.  Admission was not based on nationality, rather on race.
