Perhaps the biggest pleasure in attending an entire season of summer-stock theatre lies in the chance to see familiar faces in show after show. If a company's actors have impressed you in the past, just noticing their names in a new program is enough to make you smile, and I've now smiled throughout four consecutive shows at the Clinton Area Showboat Theatre (CAST). By this point, I'm so happy just seeing Katherine Walker Hill and Nicole Horton and Chris Amos and Craig Merriman and Patrick Stinson and Sandee Cunningham and Michael Oberfield and the rest of CAST's 2005 ensemble that it barely matters what show they're in; with actors this enjoyable, audiences are all but guaranteed to have a great time. (It's a wonderful argument for remaining faithful to a theatre ... and for purchasing season subscriptions.)
