Well, if you are in S. Oregon, I HIGHLY recommend you do NOT 'rely' on it ( or figure in the 'end' it will be 'right') At the very least, use your brain.... a few yrs ago, a young family (the Kim family) out of San Francisco was on vacation and after being 'north' decided to go to the coast here in Oregon ( south coast)... Did they pay attention to all the exit sings as they headed south that state 'clearly' Oregon Coast? No their tom tom, garmin, mapquest ( whatever it was) 'showed' them the way to go, and THAT was all that mattered to them......... (hence, my use your own brain comment) It took them over Bear Creek, NOT an 'improved' road........... Can you get from here to there over that road? Yes........... ( BUT! NEVER in the fall, winter or early spring, and take Dramamine
) They ended up stuck in snow, the Dad took off, to 'find help' after a couple days and ended up dying from exposure... The Mom was still nursing the baby and kept her toddler alive by nursing him as well...... Days later and several hundred thousand dollars of search efforts found them........... Truly tragic, and terrible............... Several 'things seem to 'conspire against them'.. But, the one quote from the Mom that I can't get outta my head, was how the navigational 'thing' showed it to be a 'good route'.........................
