Summer activities?

OK, readers, it's your turn to help me! I know that there are a lot of Jewish summer camps available, but with few holidays - most of them somber - until Rosh Hashanah, what do you do to keep your kids in touch with all things Jewish? Honestly, with a newborn, just lighting Shabbat candles without having the older son knock them over seems like an accomplishment. But I'm wondering what others do over the summer... Please let me know your ideas.
