Supporting these institutions is supporting the Jewish community. Now, it may sound like an expensive prospect, but many events have cheap student tickets, and quite a few are free to the public. You don’t have to go every single week, but once a month or so is more than enough to get the benefits, especially if they are topics you yourself are fascinated by.
There will be a lot more events in the near future, a quick look online or in this very newspaper can glean you lots of summer lectures. I’ll be going to a few and I hope I won’t be the only young person there.
