I usually come from Walla Walla so I'd be passing through Dayton. The only time I fished the Tucannon (last year)was to go up the Tucannon road. I had some luck a little ways up that road but found lots of barbwire obstuctions. Next time I'm up that way this year I'll look for Darver Tackle.
Come'on jbwood, sounds like a road trip to the home country. :smokin
