Did the Hope > Spences Bridge > Merritt > Princeton > home loop on Sunday. Very light traffic up the canyon; typical superb breakfast at Fat Jacks; excellent road conditions on Hwy 8 ( just some dust near the centrelines, but no gravel or sand at all); perfect surface conditions on 5A south to Princeton; there's a 2-3 kms gravel section on Hwy 3 about 15kms west of Princeton, otherwise all good, altho moderately heavy traffic on a sunny Sunday afternoon; plenty of snow beside the road up at Allison Pass, but not overly cold and the road is fine. One patrol car running radar on the 4 lane section west of Princeton (no surprise), otherwise no sign of 'trouble'. In other words: good to go!
(Sounds from filterwrench's report that the Duffey needs a bit more time...)
