Might as well join the fray here with some notes about what I did last week.
From mid-2017 through 2019 I found myself flying places for work a fair amount, this left me with a good amount of airline miles burning a hole in my pocket that I'd never used. Well, last week I used them to fly first class to Phoenix and drive in a big loop around the southwestern US.
Routes newly clinched: AZ I-10, AZ I-10 BL (Quartzite), CA I-10, CA 111 (Palm Springs), CA 210, CA 134, CA 1, CA 9, CA I-880, CA 238 (Castro Valley), CA 4, CA 207, CA 203, CA US6, NV 374, NV/CA Daylight Pass Rd, CA Badwater Rd, CA 178 (Shoshone), NV 372, NV I-215, NV I-515, NV 319, UT 56, UT I-15 BL (Cedar City), UT 148, UT 12, UT 95, UT 162, CO 41, NM 17, NM I-25 BL (Springer), NM 585, NM 68, NM 30, NM 501, NM 333, AZ 473, AZ 373, AZ 188, AZ 24, AZ 202
Couple other things of note:
1) I like how this gives me a majority of the single digits in CA. I now have CA 1, CA 4, CA US6, CA I-8, and CA 9 all clinched.
2) Two of these newly clinched routes (AZ 373 and AZ 473) are routes I have sole claim to among TM users - no one else here has been on any of either. I am also currently the only person to have clinched the newly extended AZ 202 (you're welcome), though I expect that will change as other users update their list files as the extension has physically been open for nearly a year.
