I linked over to St. Thomas More priory and found the curious notice about not calling the priory “before 10 AM or during meals”. They must take their meals very seriously there. “I have a dying relative, so please come after brunch.”
Since that chapel is served out of Sanford, it’s possible that they rotate in one of the NO priests from there, so you might have to check each week. If you have no other option, you may be stuck with memorizing Father Rigi’s face and if you show up there and see someone else to just refrain from Holy Communion. Of course, even if Father Rigi is there, if he distributes Holy Communion from a ciborium in the tabernacle, you may not know. It’s a shame that one has to deal with the SSPX Russian roulette of NO priests.
