us living in the South, we don't have snow , ice or any sort of Winter weather (Right Roger?). So, when the white stuff falls (And it comes fast and heavy sometimes) people freak, run off of roads, get stuck and some die due to inexperience or the improper automobile and the knowledge to use it.
After all, they're in a National Park where it's safe to hand feed the bears, climb on wet rocks and do things like head off into the woods with a t-shirt, shorts, sneakers and a bottle of Evian in your back pocket. (Don't try this, please!)
Snow is a driving hazard, you can't drive anything on "Black Ice" and 4x4's don't go everywhere, contrary to popular belief. Not even rental cars, even though we seem to push it at times.
Either close the roads until safe or the Rangers, and other Park services, become wrecker services, ambulance services and body bag loaders. That converts to mucho over time on limited budgets.
Make sure that the roads are open, be ready for anything and remember... that Highpoint will still be there the next time around. Well, Mount Rainier???
