5 of us are going jan 23- feb 2nd the 23 rd and 2nd are the driving there and back days. Just worried if need chains for the mountain passes so we don't have to find on way or not allowed to go over. were doing west Yellowstone islands park area
if it was me and your worried, just bring the chains, they don't take up that much space and then you will have them??
odds are you won't, as they said, when roads get iffy, they close them , then once cleared or re opened should again be fine?
but snow storms can happen at any time, so having things like chains is never a bad idea in snowy/icy places??
SOn't think you will need them for teh trailer however, as if its bad you need chains, your not going to be going that fast
but having brakes of the trailer, and then chains could only help LOL
have a great trip, its a great place to ride out there and this winter should be another good one, the ways it seems to forming up now?
