Within reasonable distance of my home are two Novus Ordo parishes, and a traditional latin order of monks, whose Masses are open to the public.
One of the NO parishes is “liberal”, the other about as traditional as one can get and still offer only the NO.
“Liberal” parish ==> almost exclusively old people
“Traditional/NO” Parish ==> old people, middle aged people, young families evenly mixed.
“The Monks” ==> mostly young families with a few old folks.
FWIW.
Hear that all the time. TLM is where springtime is.
