Don't drive in Cincinnati when: it's raining, it's cold, it's snowing, it's sunny, it's dark, it's foggy, it's early, it's late, it's dark, it's hot, it's goign to rain, it's going to snow, the Bengals are/aren't playing, the Bearcats are about to play, the Reds are in town, there's a holiday coming up, there are sales at discount chains, or there's a storm coming. Otherwise, it's perfectly safe to try to drive, just avoid I-75 if you can.

If the printer/scanner/photocopier is on sale for $39.99 at Target, there's a good reason. Or, there are a number of good reasons. Don't do it, it IS too good to be true.
Nearly everything is cheaper online now, especially if you can get someone else to spring for Amazon Prime.
The dissertation will not write itself, no matter how much you want it to: hint, hint.
