Catholics didn't used to have Vacation Bible School. We had day camp, or youth group, or nothing at all. It was great fun, we went swimming, went to the beach, roller skating, did arts and crafts, and had a big campout on the last night.
Now alot of our churches are having Vacation Bible schools, but my local one doesn't. So I take my son to the Baptist church's VBS. It is a great ecumenical and community building experience and I just love the Baptist preacher and his wife, who also just happens to be one of my favorite authors. Oh, and the kids have a lot of fun too.
The ladies in charge of arts and crafts really outdo themselves with clever activities. The games are very clever and exciting, the snacks are fun and imaginative. The children learn a new Bible verse each night, and work on songs and dances all week, in order to put on a delightful production for their parents on the last night.
