My Garmin Nuvi 465 wants to take us south from Denver and turn west on 160 in Walsenburg through Fort Garland on CO 159 and continue in New Mexico on 522 to Taos. This route will work, but looking at...
Well...I think I have answered my own question. The GPS is taking the shortest/quickest route. Per Google maps, its 4 hrs 8 minutes/267 miles via 160/522 (the way the gps wants to go) and 4 hr 59 min/293 miles via the way I thought would be faster cuz you're on I-25 longer.
Looking at the routes highlighted via Google maps, I can see why the one is shorter. Hard to see that on paper and impossible on GPS.
