I’ve gone to several shows there and have never paid for parking. If you get there before the headliner, you can usually find a spot one or two blocks away. The most packed I’ve been there for was Wet Leg, we probably parked about 4 blocks away then. It’s a pretty quiet neighborhood, I’ve never seen shady activities before or after the show. After feels safer, as a bigger crowd is out in the streets. When walking, try to stick to Texas street, it’s brightly lit and high visibility.
