I guess this belongs in this thread. I just saw that the injuns in South Dakota are setting up roadblocks to stop bikers from going to Sturgis via roads that go through reservations. Apparently there are some big legal issues with this. If it were fed/state land, it seems it would be illegal to stop someone because they were on a motorcycle or because of the way they dressed, but let others through, all because of COVID.
Maybe they're turning everyone around, but the news snippet made it sound like just bikers.
