Growing interest in the Tridentine Mass

In Baltimore, the popularity is growing. This article is an interesting read. I think promoting the Mass is the biggest draw. Some people in parts of the country probably do not know it exists. It could also be fear they wouldn't know how to participate that keeps some away. Regardless, it is good to see it thriving in a part of the US. Logically, how many priests will be ready after the moto proprio to offer the Mass? Maybe the desire will be enough to drive them to learn.
