Cameras are fine. Cell phones too. But if you're planning a trip to the Jan. 20 inaugural ceremony of President-elect Barack Obama, be warned: There'a a long list of items that won't make it past security checkpoints.

The swearing-in ceremony is an outdoor event held on the West Front Lawn of the U.S. Capitol.

The list of prohibited items on the Capitol grounds includes the obvious -- firearms, explosives and knives -- along with some head-scratchers, such as strollers.

Strollers take up a lot of space, and they're made up of hard metal or plastic. Anything like that is not permitted, said Carole Florman, communications director for the Joint Congressional Committee on Inaugural Ceremonies.

And be prepared to stand in what is typically frosty weather, because folding chairs won't be allowed either.

Here's a partial list:

• Firearms and ammunition (either real or simulated)
• Explosives of any kind (including fireworks)
• Knives, blades, or sharp objects (of any length)
• Mace and/or pepper spray
• Sticks or poles
• Pocket or hand tools, such as "Leatherman"
• Packages
• Backpacks
• Large bags
• Duffel bags
• Suitcases
• Thermoses
• Coolers
• Strollers
• Umbrellas
• Laser pointers
• Signs
• Posters
• Animals (other than service animals)
• Alcoholic beverages
• Other items that may pose a threat to the security of the event as determined by and at the discretion of the security screeners.
