Therefore they do not as a rule sell tickets to anyone who lives within 50 miles.
Why 50 miles? If it is Orthodox, walking distance is much less than 50 miles. If someone lives 15 miles away and is coming to the shul, he surely is not walking in. If he is Orthodox, he must be a visitor.
Visiting out of state relatives may receive tickets when they provide a letter fro their home shul that they are members in good standing with dues paid up to date.
What does requiring such a letter accomplish?
College students are welcomed at no charge, just asked to call in advance and be placed on the seating chart.
What about Yeshiva students?
P.S. These policies seem to be generated from a very MO shul.
