It can and does happen!
Pat O'Rielly a Brother LXA from FIT. Fl. was attending Grad School at Un. Wyoming. Some guys saw Him wearing His Letters and stopped Him to ask about what they ment.
They started a Local interest group and are now a Full Chartered Chapter.
If there is enough interest by a large enough group, present yourselves to The College and The National. I did just that in 1965.
Have been involved for 40 Years.
