Having recently bought a car after shopping for weeks for one, I have achieved total mobility lol. Living up in the hills certainly hampers my desire to go where the distance is far too great to walk and a 40 min walk to town isn't the most fun thing to do if the weather is awful (as it usually is).
Up the hills, we get frost and ice a lot more often. We had ice for 2 weeks straight a while ago...during the coldest June in 34 years. Walking down to campus on icy ground is certainly an adrenaline rushing experience where you're slipping and sliding down a very steep hill with high chances of falling over. It's really like skiing without skis and no way of stopping (except by falling over or if you're lucky, by grabbing an available lamp post). Even on flat ground, if it's icy, your feet won't stay in one spot. Snow isn't bad...ice is horrible.
I suppose driving would be pretty dangerous, but it seems that the roads where the cars run dun ice over as much...and if there was ice, it would have been gone relatively quickly, unlike the sidewalk where ice can happily stay the entire week.
But, it's pretty up the hills...and quiet...like you'd only notice the neighbours are having a party if there are more cars parked around than usual. Wish it would be a little warmer though!
