I'd scalp the whole package. There's no way someone could get me to go to detroit without threatening me with loss of job or something. Go there voluntarily. No way. too many moslems there.
I also would never go to New York City, various neighborhoods of Cincinnatti, Pittsburg, Philadelphia, Most of New England (excluding Maine), Chicago, San Fran, South East DC after dark (or across the river at any time), St Louis (if I could avoid it in any way), Austin TX, Madison WI, LA, and probably ten or twenty other major cities.
I try to avoid democrat areas in any state and try to avoid blue states entirely.
Let me modify my last answer a little. If the Packers were playing and I could go in a large group of packer fans (50 to 100) then I may consider going. But since the game is always televised why bother putting up with the denizens of detroit at all.
The people who live in these blue states are Americans as well and there a large minority of conservatives who live in these states. Do carry so much hate in your heart, it is not healthy, and it is unAmerican.
You left out New Orleans. :-)
