Back in 2007, as a college freshman free to live as I pleased, with a love of highways and a car that needed driving, I embarked to drive every mile of state highway in Washington. At that point, a monster was born. In 2009 I moved to Wyoming and clinched that system. In 2011 I moved to Arizona and clinched that system. In 2013, I moved to Montana and finally clinched the Idaho system in 2014. In 2015, I went to Delaware just to clinch that highway system. In 2016, I finished Montana and moved to Idaho, allowing me to get started on Oregon. While doing all that, I managed to drive and photograph at least a little bit in most of these United States. I’ve recently finished driving all of Montana, and look forward to getting started in earnest on the Oregon system.

As for the remainder of content, I currently have a couple year backlog on getting things posted. I focus on getting Oregon stuff up immediately, and then things go in reverse order by state.  I’m really trying to get caught up and am working through photos from 2013.
