Detroit Lake, just 20 minutes south of Breitenbush, is also a beautiful sight to see. The U.S. Army Corps of Engineers flooded the old town of Detroit to make the reservoir for hydroelectric power, generated by the two damns just west on Highway 22 (back towards Salem). The uppermost dam is a lot of fun to check out, and depending on how low the water is, you should be able to walk around and explore the floodzone. On clear days, you can see the peak of Mt. Jefferson between the surrounding hills.
For those who'd prefer to stay in Salem and travel to the ceremony, this is a fun and kinda creepy fairy tale themed amusement park that's been open in Turner, OR since 1971. A staple for kids who grew up in the Salem area (so Michael hears).
