Dang! I missed that one the few times we’ve been through Marsing...mostly went through there because we detoured at Burns, OR, to get a Basque dinner in Jordan Valley. From there, we usually took 78 down to Bruneau, then over to I-84, instead of just going over to Nampa.
We had to do a lot of traveling back & forth between Medford, OR and South Dakota, until we finally got the Oregon house sold, so took a lot of ‘scenic routes’. There isn’t an east-west route across Wyoming, including several unpaved ones, we didn’t use at least once.
But NEVER saw Chicken Dinner Road. :-(
Yep, you have to take Hwy 55 to Nampa to see the intersection there.
