Something similar about where I live in Harrisburg and where I stayed in Phoenix last month is that an interstate is only 1/4 mile away from either spot. They snake all around Harrisburg, making it necessary to get on the interstate just to go to the grocery store. I’m not used to highways being such a major feature of cities.
A big difference in these automobile-filled urban centers, though, is that Phoenix drivers pay attention to bicyclists. Moreover, if there’s not room on the road, the sidewalks are a reasonable option for biking. Not so in bankrupt Harrisburg, where broken glass bedazzles the cracked and crumbling sidewalks.
