I have been commuting from 12 to 18 for over three years. Currently at work now. There is a definitely a microclimate by the rest stop. There are a lot of unexpected snows that I came across. The most different part is the speed of other vehicles on 89. They are consistently 15-20mph over the speed limit even in shitty conditions. I feel like 89 is worse than 93 when it comes to shitty drivers. 93 just comes to crawl a lot. So maybe that’s why you don’t notice the shittiness.
