My recollection for 2020 was that there was little interaction until it got close to the event and registered rider was listed on the event webpage. Maybe try Chuck Bramwell,
ctcbounces@caltriplecrown.org, over at CA Triple Crown or LA Wheelmen (can't remember the guy's name, Ira Kucheck? but he was helping Jim in cancelling the event due to the disease). Your post reminded me that I needed to register (been only checking Joshua Tree). Hope to see you on course, I'll be on a Motobecane Ti.
