You was wrong mister!
I stopped at Les Schwab to pick up some chains, fuckers had a big sign on the door saying they don't do chain returns earlier than April... their loss, went to Walmart and picked up a set of chains I can return whenever and wherever, and then went on my merry way.
It was snowing in the Shasta Mountains, but as I had thought the heavily traveled road was nothing other than wet. But the main thing I was concerned about were the Siskiyou Mountains, and I didn't even realize when I passed through them - no snow, no ice, nobody checking to see if I had chains in my car. I seriously didn't even realize until well after I had passed them, I don't know why the ODOT website indicated it was snowing earlier in the day there because the roads weren't even wet when I was there 2 hours later. So I guess as nicely designed the ODOT TripCheck website is, it isn't worth squat in helping you plan your trip.
Still glad I decided to stay in Portland though, I got worn out earlier than I did the previous day... and I can take a leisurely drive home tomorrow and not arrive at 3 in the morning. Plus, Voodoo Doughnuts tomorrow!
Oh, and definitely glad I didn't ship my car... saw a bunch of trucks transporting cars, and one of them had this Escalade at the back which, I shit you not, was totally untethered at the front axle and was teetering up and down on the rear axle like a seesaw because the trunk bit that protrudes out from the rear axle was just hanging off the back of the transporter. I don't even know how to explain it properly it was so out of whack.
Anyway, I guess this thread has run its course - I'll be home tomorrow after 2.5 long months and some 4,600km of driving. Thanks all.
