I've only made two trips since the middle of March, both of which were between northern VA and eastern PA that I've done hundreds of times before. I did manage some new mileage though.
New clinches:
US30BusTrkDow in PA (completely by accident), US202AltTrkNor in PA, PA238, PA340, PA341Truck, PA392, PA463, PA921, MD134, MD139, MD162, MD170, MD198, MD652
New mileage on still-not-clinched roads:
US30Business (Downingtown) in PA, US322 in PA, PA23, PA23 Alt Truck (King of Prussia), PA24, PA74, PA896, MD176, MD648
Between the pandemic and vehicle problems, both of which have heavily curtailed my travel, I expect most of the rest of 2020 and early 2021 to have very little, if any, more new mileage from me.
