I also first encountered creationism in college in the early 1970's. There were some (as they were referred to by others) Jesus freaks in my circle of friends, and after I'd known them quite a while, at least a couple years, one night at dinner the subject of evolution came up. Naturally I was surprised to discover they rejected evolution. The subject never came up again, and I didn't think anymore about creationism until the late 1980's when I became aware of it as an issue affecting public schools.
