Re mileage: I've put on about 3,500 so far - about another 1,200?? to go until I get home. But all on pavement, so still a noob. The Google says a direct route would have been 2,900 miles and 46 hours.
I hope to be in White Salmon Sunday. Depends a little on how far I get Saturday - and that depends on the weather at Glacier NP. I'm not doing Going to the Sun if it's icy snowy up top.
Be glad to let you drive the rig. I've been wanting to check out yours and talk with you about the stuff you've done to it.
It is better to have ridden and crashed, than to have never ridden at all.
