Michael W's advice to "add Mr Tuffy tape if the streets are in bad condition" is something I should have thought of. I've used Mr. Tuffy on both my bikes since I got them, and from the looks of the tape, it's saved me from many a puncture. Thanks, Michael.
And I also second carrying a cell phone if possible. Pay phones are getting scarce in the US (and in the UK too, from what I gather). The peace of mind is worth the extra few ounces of weight.
thbirks's "there is a difference between places that are just run down and in poverty and places where you are in danger from riding through" is another excellent observation. If you've lived in Cincinnati for long, you're probably already a good judge of those areas.
You know, I think Oscar's "Dive in and swim" may be the best advice of all. (Just remember, you get a higher score the less you splash!)
