Clothing/Shoes/Weather Gear: the weather here changes here all the time. Basically if its winter, it will be cold and wet. Pack to stay warm, with extra shoes in case there is snow. Fall and spring is pretty much "light jacket" weather. Summers range, but stay pretty hot. Just remember, if you don't like the weather, just stay an extra day!
If going between December and March (inclusive), bring a down parka.
Miscellaneous: Remember to pack those nail clippers, underwire bras, aerosol cans, pocket knifes, etc. in checked luggage or you'll have to give them up at airport security.
Clothing/Shoes/Weather Gear: Um... summers are generally warm and humid.. you're still in the Ohio Valley here. Winters are snowy and cold (not too much snow). Basically the weather is like Louisville's, but just slightly cooler and maybe slightly more snow.
Luggage and bags:
Depends on how long you're staying and when you're staying.
Clothing/Shoes/Weather Gear: Shoes. Definatley bring walking shoes, there are many sights to see in Cincy and it's easier to walk (at day) to different destinations, than it is to drive.
Weather gear. Bring umbrellas!!
Camping/Beach/Outdoor Gear: Bug spray. There are always lots of bugs in Cincy.
Miscellaneous: Anticipate (summer) hot days, and cool nights. It's always pretty chilly at night because of the River. During they day it can get to about 80-90.
In the winter, BRING WINTER COAT! The bigger, the better. It can get extremley cold.
For staying in the city I took warm clothes for the winter. It does snow there and it will almost definetly rain in the winter. So pack something that is warm, and take a lot of clothes that you can layer. For traveling across country, which we did in the summer, it is best to just bring something extremely comfortable. You're in the car all day, so no one sees you.
Photo Equipment: You can get batteries anywhere, and plugs are abundant in the hotel rooms. Just be sure to hold onto your camera. Nothing happened to mine, but as with any large city you may stop in theft is always a danger.
Don't forget your camera, film and other supplies. You may never be back here again, so take a picture.
ESPECIALY if you visit the Zoo.
