Friday night services at the YMCA
By 1943, there was clearly enough interest in Jewish services that the YMCA facilitated Friday night services for those service men who could not go on Saturday. This suggests that there was a moderate level of observance-- students who would go to services weekly, but who did not have an objection to working on Shabbat. It should be noted that this took place during Bowman's Jewish quotas (see footnote 14).
