I just now noticed your posting. Usually there aren't many in the track and field part, that's why I didn't notice till now. Anyway, I'm in Nebraska/Iowa, where we pretty much have to get our own bookings. I'm fortunate that I also do football and basketball and get asked by those AD's to work their meets as a starter. That would be one route for you to go.

Are you in a metro area where a big school district might have a district-wide coordinator for athletics and/or PE? If so, contact them. You might have to pick up some middle school meets or undervarsity meets at the bigger schools to get some experience.

As for experience, I did run some track in high school, but hadn't been around the sport except as a spectator before I got my registration as a starter. Sometimes I felt like I wasn't doing the right thing, so I would contact another football/basketball official who also is a starter for track, as well as my college PE instructor who is a starter as well, and bounce some stuff off of them. Eventually, they gave me some leads as to some bookings as well.

You might have to go at it slowly, but eventually, with experience and knowledge, you'll get there.
