Question about going to a track day.

Hallett motor speedway is the closest track to me and I have never done a track day before but want to start. I can’t find any info about just going as an onlooker. Is there an admission fee or can I just go?Thanks. via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/cc4xko/question_about_going_to_a_track_day/?utm_source=ifttt
