Since CHM went down, my main addition was a few segments between here and Florida last Christmas:
—Clinched I-795 in North Carolina
—Drove part of I-140 near Wilmington and the portion of US-17 connecting the old road to the new one. The previous time I had been through there was May 1993 and I'd gone straight through the city. (In the course of updating my .list file I discovered I had entered the data erroneously and it showed I'd gone around on the new bypass, so I've fixed that.)
—Clinched the new SC-31 bypass around Myrtle Beach.
—Nipped off a piece of SC-544 after exiting SC-31, then nipped off about two-thirds of SC-707 as a route down to Murrells Inlet (this was probably a mistake; US-17 would likely have been faster).
—Knocked off most of the portion of US-17 I hadn't yet driven in South Carolina, everything from SC-707 down to the southern junction with I-526. While we continued on down back to I-95, I'd already driven that segment a year or two earlier. But it's in much better shape now that the widening project is done. I have yet to travel the segment between US-501 and SC-707.
—Clinched the existing segment of FL-9B (Future I-795). This is an utterly trivial accomplishment given how short that road is!
Since that trip, I've picked up a few missing segments of US routes in Virginia (US-17 between Marshall and the turn for Great Meadow; US-522 from Front Royal to US-211 and from Sperryville to Culpeper; probably one or two others I'm not remembering).
Travel for later this year:
—We have a trip to Albuquerque and Phoenix planned for late September. Flying both ways via an open-jaw on Southwest and then driving around between the two. After four days in Albuquerque, we're driving to the Valley of the Gods in Utah and staying a night at the bed and breakfast located near the foot of the Moki Dugway. We will certainly drive the Dugway so I can take pictures from the top (maybe go to Muley Point if the weather permits, but we'll see), then drive back down because our next destination after there is the Grand Canyon via Monument Valley. After a night at the South Rim, we're headed to Phoenix to visit my brother-in-law for four days before flying home. I've never been to any of these areas before. I figure I'll make a point of clinching I-17. Beyond that, I'm not focusing on clinches so much as I am on picking scenic routes and doing the Moki Dugway and maybe the 17-mile unpaved road through the Valley of the Gods if weather permits.
—We have another Christmas trip to Florida planned, but instead of our usual plan to visit my sister-in-law in Viera, we're visiting my brother-in-law near Miami and our nephew in Fort Myers. The added mileage made it difficult to work it out to drive one way and take the Auto Train the other like we usually do because of work calendars at the end of the year, so instead we're taking the Auto Train both ways. This works out well for me because the depot is in Sanford, so I can knock off the segment of Florida's Turnpike between somewhere in Orlando (not sure whether I'll use I-4 or loop around some other way) and Fort Pierce, which is a long segment I had figured I was unlikely ever to have reason to drive. For the drive over to Fort Myers I might finally use US-41 across the Everglades. I've been as far as Shark Valley on that road. Then for the trip back to the Auto Train I'm considering US-27 up the middle of the state, or alternatively going to Tampa and knocking the Selmon Expressway off my list (but then we have to go up I-4). I have one piddly section of I-75 left to travel in Florida, the segment between I-4 and the northern junction with I-275, and had we driven one way I would have knocked that off, but now it's not happening. Oh well. The train is overnight, so it basically saves us a full day's drive at each end.
For obvious reasons given where I live, I have a lot of unmappable travel on Virginia state routes, but the thought of reconstructing all that if/when that system were to be added makes me shudder a bit. I know I'll never remember all of it because a lot of it came before I thought much about keeping track of this sort of thing.
