I've found one by going to smaller EDM/DJ sets on weekdays and talking to people - it's not a huge crowd so people tend to chill and chat. Never ended up going to the actual event - it was more of a local burner/art event, but it was definitely a word of mouth kind of thing
Yeah, regional burns are definitely my jam. I guess I just gotta ask folks what other events they are going to whenever I'm at one. Yay network effects!
