Looking at the Tradito directory for California, being in Northern California myself, there are many errors that prove that the directory is in need of an update. To begin with, three diocesan TLMs in and around the San Francisco Bay Area are not listed at all. More importantly to those who are sympathetic to Traditio, a major independent Mass center in San Jose that includes a flourishing school academy is also not listed. In addition, the SSPX Retreat House in California is located in the city of Los Gatos, not in Santa Cruz, as the directory states. Apart from this, the directory incorrectly lists the time of the Sedevacantist Mass in Martinez. Instead of at 11:00 am, the Mass at Martinez is really at 12:45 pm.
Apparently, Fr. David Nichols of the SSPX, who currently resides in the Society retreat house in Los Gatos, celebrates Mass in 4 different SSPX churches in Northern and Southern Calironia all at the same time on Sunday. He does this while also flying to celebrate Mass in Nevada or Colorado every first Sunday or something if I recall correctly.

If there are these much errors for California, there could be more errors in the listings of TLM Mass centers in other states as well.
It is also very interesting that Traditio recommends Fr. Perez at Our Lady Help of Christians in Garden Grove. He may be independent, but to Traditio standards, he is not a validly ordained priest since he was ordained by a cardinal who was consecrated a bishop in 1983, way past the 1968 cut off.
