The link to Solo Nationals Paddock is paddocknow.solomatters.com. It's live now for looking and it will open at 9:00 p.m. Eastern (8:00 here) for individual paddock spot selection. The STL paddock is pretty far back from the courses, on the street side, not on the airport side. I can't see row numbers (looks like we're #17), and I couldn't see a way to search by name or region. Hopefully those options will be available later.
