Sorry for not being more specific, but how busy it is controls whether I'd be doing anything or not. My brother's family lives down that way in The Dalles, so either pleasure boating or fishing is a possibility.
If CR is really busy with pleasure boaters, fishing boats, etc. there really isn't any reason to think about towing a boat 4 hours. However, if it is not, then I can entertain what species I could go after based on regulations.
