I believe I would take what I could carry and walk out of that area. Inconvenience for a while is worth your and your family’s survival. Look at it as an adventure to better times. Many immigrants arrive here with nothing and have great lives.
Yes, I'm sure you would, Utah is a very pretty state with pretty cities. Where would you walk to? And once you got there, where would you live? You couldn't sell your house so you had to abandon it and since you're elderly and on limited income, as many of the trapped Detroit residents are, what do you think you can afford once you've reached your city of choice?
