Free Speech Zones In National Parks

I’m an employee in Yosemite National Park, who also lives inside of the park year round (bigger community than most people realize, around 2,000 employees live inside of the park) I am not a government employee, I work for the concessionaire.

There’s an employee pride parade that’s been going on since 2016. It’s been getting bigger and bigger, and last year was our biggest turnout with about 200 people! We start at the employee recreation center in curry village, and walk to Yosemite falls.

Last year a few news sources got photos of the parade and published articles. The right winged we’re not happy about it and made a BIG fuss.

Park services response this year was to deny the pride parade permit, and establish free speech zones. I know this is more of a legal loophole for them to deny us our pride parade without violating our first amendment rights, but everyone is still planning on doing the walk as a group regardless. What can we say/ do if we are arrested (which seems very likely with how park service is responding) for being outside of the free speech zone (which btw, is a small dirt area that’s about 10x10ft near the visitor center)
