Rode to Prudhoe June 2016, was 9,200+ Miles round trip, gone 22 days and it rained every day, some days it rained all day, had camping gear along but never used it because after riding in so much rain we really prefered a nice dry motel and yes that got expensive ! Took a heated jacket along but never used it, the coldest temperature we saw was 30 degrees on Gunison pass, we were both spinning going up Gunison in the rain but we were lucky enough to make it, from Gunison to Prudhoe the road was very tough going with lots of rain and wind, we had made reservations for a room in Prudhoe $230 a night but that included all the food you could eat and free laundry, we got there about 9pm and there were 2 young ladies checking out, they were riding bicycles to Fairbanks ! They asked if we could haul some of their gear to Coldfoot for them but we said no because we were already overloaded with our own stuff, when we got to our room my buddy says check the weather forecast , well iPad said rain and snow for the next 3 days, next morning yup it's still raining and very windy so my friend is worried we might not make it over Gunison pass so he says let's see what Carlile trucking would charge to haul our bikes to Fairbanks, so we walk over there and ask, $160 per bike wow that sounded great to us ! Then we walk to the airport $350 each so ok it's a deal, the bikes showed up in Fairbanks the next morning just like they told us, it was an extra $500 but in my opinion well worth the money to avoid the possible problems, the next day Prudhoe got 6 inches of snow. On the way up My low fuel light was flashing for about the last 10 miles before prudhoe so i figure i had plenty left but my buddy was riding a 800 GS with only a 4 gallon tank so he had to stop and add extra gas he was carrying before we got there. Bears we saw 12 grizzly,brown and black this time and they were mostly in canada , in 2007 we saw about 30 and on that trip we mostly camped, we had fantastic weather for our 2007 trip. After the early June 2007 trip I thought maybe early June was the ideal time to ride to Alaska but after this trip I think July or august might be a better choice because a lot more of the road construction might be done, we are planning to go again in 2018 but it most likely won't be in June.
