You may exercise your First Amendment rights only in the parking lot
While sifting through some old photos yesterday, I found this image taken at Great Smoky Mountains National Park in the Clingman's Dome parking lot. I've seen a few of these signs at national parks in the West, but none so prominent as those appearing at Great Smoky.
A " 'First Amendment' Expression Area" was also designated in the parking lot of one of the visitor centers at the park.
These signs, the implications of which go without saying, should spark much discussion...
(Why, pray tell, would they put the First Amendment in quotation marks?)
