I have been racing cyclocross for several years and it’s one of the funnest things I do all year.
I race mostly in the MFG series because these are the closest, but I’ve done other series’s races and several one-offs. If you never seen a race, it’s really fan-friendly and you should check it out, it’s quite the spectacle.
