I’m in the far northeast corner of Oregon... about 2 hours from Idaho to the east and 2 hours from Washington to the West both using I-84. I am assuming you are getting off of I-84 in between Meridian Idaho and Onterio, Oregon, then traveling south west along the Oregon/Nevada borders to get to K-Falls then heading north through Bend up to MT Hood NF. If you come a little further north and exit I-84 in baker City, Oregon and take HWY 7 to Johnday, there is a lot of amazing fly fishing along the Powder River, John Day Rivers, and other streams and rivers through Central Oregon and then all the way up to Hood River where you cross the Columbia to start the WABDR up north to Mt Rainer NF.
