I don't know, I used to make similar sorts of treks daily, but on county highways (speed limit 55). No sidewalks. Uneven sides with drops.

I just gave cars berth, and wandered into the ditch when necessary. So the ground is uneven; never bothered me any. I didn't feel particularly restricted; I just went where I wanted to go, however I needed to do it. Probably not the best place to walk with your kid, I'll grant.

What did get to me was freeways; the idea that you have this huge swathe of road that's just straight out illegal to cross on foot.

What's really limiting, though? Not having access to a vehicle when you need one...
