im joining a cousin on a one week oregon road trip in early january. basically will be a north-south loop: portland-bend-medford-springfield-portland. it’s his consulting work trip (industrial safety & hygiene) and he invited me to tag along. he is a beer nut. we’ve never been, flying in/out pdx from n.e. and familiar with winters but not oregon’s. any thoughts/suggestions/advice/warnings? we will rent something awd, do rentals there come with snowscrapers? should we buy some tire chains or other emergency items? how are main roads in winter? is crater lake prudently drive-able? we will dress appropriately for cold weather. he has already spotted some beer places at overnight stops (uber to/from hotels). we will stay out of portland city proper, just pdx and his job site in beaverton. thanks!
