Yeah. I'm pretty much trapped on this island that is my house.
There is a side walk behind my house that can take me to the mall (an hour and a half walk if I really try one way) or the train station (45 minutes walk which isn't that bad if a tad dangerous because there's no side walks in...
We don't have a block, we live on a 2 acre property right on the edge of a very busy road with a ditch for water drainage instead of a side walk.
The only way to walk around here is in the road, and that would be the equivalent of suicide.
