I’m flying out to Portland November 15th and driving back with my brother who’s moving back to Michigan. We’re leaving the 18th and want to be home on the 24th. I know we’re taking a more southern route bc of weather but I’m looking for any cool things to stop and see along the way. I would like to do a hot springs and if any gem mining/gold digging or underground cave/waterfall tours, something like ruby falls would be really cool. I missed that when I drove home from Florida and have always regretted it. Any and all suggestion of cool things to see would be appreciated, I’ve never gone any farther than Chicago. I know we’re looking to get out of Oregon really fast bc he’s lived there for over 10 years. Thanks.
