Hum, weekly supermarket trip is about 40 miles round to the nearest large supermarket. At my current level of (un)fitness I *might* be able to manage 15 miles/day...
There is a small Co-op in town only a 5 mile round trip but they don't stock a number of things we buy regulary. The really big snag is that for both it's uphill all the way back home. Overall about
300' from town and about 1300' from the supermarket but peaking at 1550'.
