Hi there knittngknerd. Being in your situation without snowchains would frighten the bejeeseus out of me too. You are correct in your assertion that the roads are not going to ice up unless the temperature is 32 deegress or lower. Black ice is scariest of all, as it is so clear that even seasoned drivers cannot see it.
Snow tires are the only real solution, as they dig into the ice and help you to ontrol your car. You would still need to travel slow as possible going up and down hill - and even on level land. As aforementioned by mousechiled, you need a certain amount of speed to get up hill - and tap don't slam on your brakes. Still, following all of this advise will not make you anywhere near as safe as you will be with snowtires.
I'd call law enforcement and ask where you can purchase a set at - or find some places using the phonebook. I'd wait until the weather is above 34 degrees or more for a couple days before driving to the store for TP, cough syrup, etc. If there is a snowchain place somewhere in town, pick them up too.
Perhaps your dad could pick these things up for you - or an understanding person from one of the local civic organizations or a church.
As for your poll, you didn't have the option that I would have chose. "Drive slowly, cautiously, during the day - and as little as possible.
