Brainstorming for Sober Activities

Hey all! I come in peace from r/Birmingham. My friends and I are coming to your city for Warped Tour weekend and making a five day trip out of it. At least one of us is in the process of entering sobriety from all drugs/alcohol and we are wanting to find some fun sober activities for a couple mid 30s dads to do! Our main hindrance will be that we are planning to be carless which means most of the nature hike type options Ive seen your subreddit recommend in prior posts may not be feasible. We’ll be staying near downtown if that helps but presumably we could uber wherever! Thanks in advance!
