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. While doing all that, I managed to drive and photograph at least a little bit in most of these United States. I’m currently working on driving the Montana highway system. Montana is a bit of a daunting system, lots of unpaved secondaries over a massive state, but it’s a journey that I am enjoying taking.

In the interest of driving highways in the entire country, I’m expanding my scope to start cranking out a state every year. My hope is to have Montana completed by summer 2016 – I have to say, without the pressing deadline of “you’re going to graduate soon” or “your plane leaves in a couple days” to finish the job, it’s taking longer than I expected.  I am at a point where I now have 41 of Montana’s 56 counties clinched, and completion of Montana appears imminent. Once that happens, I’ll be in the unique (?) situation of having no new state highway to clinch within 450 miles. I’ll cross that bridge when I get there, and I’m not really sure what the answer to that is. It may be Utah. It may be something else.

As for the remainder of content, I currently have a couple year backlog on getting things posted. I focus on getting Montana stuff up immediately, and then things go in reverse order by state.  I’m really trying to get caught up and am finally through 2012 stuff.
