Im going on a school trip to washington dc what should i pack? I will be there 3 days and 2 nights!!!!!!?

I will be there in October so i need to know what the weather will be like.

If it's early October, it will likely be warmish (60s-70s) and you should be able to get by with a couple pair of shorts and a couple pair of pants (one pair jeans and one pair nicer slacks in case you go to a nicer place for dinner one evening with your group). Tops can be a few long-sleeve and a few short-sleeve, with one being a bit dressier to go with your nice slacks. Pack one pair of sneakers or walking shoes, and one pair of slightly nicer shoes that go with your nicer pair of slacks. Leave behind your flip-flops.

Also pack one light-weight jacket.

If your trip is late October, forget about the shorts and the long sleeve tops, and add a sweater that could go under the jacket if the weather gets windy and cold.

No need to worry about snow--the earliest it snows around here is mid-November, and even that is unusual. Rain is a likely possibility in October, though, so pack a rain slicker.

Check the weather channel.

You know what they say about condoms - better to have them and not need them, than to need them and not have them.

Clothes, toilet kit (toothbrush, comb, shampoo, etc), a camera, stamps, cash...buy postcards and send them to friends.

well, just normal. Clothes, toothbrush, makeup (if you wear it) 2 or 3 pairs of shoes, socks, the essentials.
You may want to go to a weather website, and type in Washington D.C. to see if they have anything about the futrue.
Good Luck! PeAcE!
If you need anymore help, feel free to e-mail me :P

its kind of early to think about this. up until recently, October was brisk, sweaters and khakis would have been recommended but the past 2 years in this area have been much warmer. so wait and check then.

Keep the main thing the main thing. Which is advise your Mother has probably already taught you; 'Be sure you got on clean underwear boy, in case you're in an accident'.

take long pants, sneakers for walking, light sweater or jacket

well d.c. in october is windy and sometimes chilly. i would pack some pants, a windbreaker(if you have one), a sweat jacket, some long sleved shirts for walking in d.c at night, and capris for the warm days.
