I grew up in and odd position having 2 chapels almost exactly apart from each other. Arcadia and Colton California. We'd attended both, but for the most part, my family attended the Colton chapel, which was more inland to the LA-close Arcadia Priory.
Arcadia could well be seen as more well off monetarily both in the chapel itself and of the parishioners who would attend; here in California people do seem to show off their wealth more. Funny thing is is that I never made any friends at the Arcadia chapel. No one seemed to want to stay after mass as much as Colton. Unfortunately the priest there, and also the head in the priory, Fr. Ward, seemed to mirror this attitude there. He was the one SSPX priest whom I'd never developed a bond with and actually whom I'd taken issue with on an entirely other matter much later on. But thats another story.
Colton, being located in much less affluent Inland Empire of Calfornia, seemed more homey to me. People were more down to earth, and my parents and I felt right at home there. There were more children and young men and women my age. Unfortunately, in hindsight, I think my friends and I at the time were trying to live in two worlds; but that also is another matter. I wish I could have been more of an example to some of the others. Too bad I didn't know about CI then (perhaps it didn't exist? 2002-2006)
Well thats my experience with SSPX chapels locally in high school, and immediately after. I'd also helped out quite a bit in the Carmichael Chapel (Sacramento) when in stationed in the military out there. I made very good friends with one of my favorite priests ever, Fr. Hewko. I assisted when I could, on my days off from the fire department, at the retreat center cleaning up; but I didn't get to do that as much as I'd wanted.
Carmichael was the place I'm talking about (hey, Carmichael/Sacramento - same thing).
A recent update from Fr. Emily says that they have a priest fly in from Denver weekly to say the Mass. Which makes no sense - why doesn't a priest just drive up from Los Gatos? One would think it is cheaper.
The FSSP parish that I described is St. Stephen the First Martyr.
