So other than the thought of summer being half over depressing me.. I've seen some fliers around and about for Greeters, and that just naturally leads me to thinking about move in day.
So first off, you may wonder just what the heck you need to bring to college. Anything you think you want, really, but don't bring all or even half the contents of your room. What I found necessary first year was a couple fans, my laptop + printer, clothes, towels + toiletries, flip flops for shower, shoes, bedsheets + pillowcases, desk lamp, laundry hamper, pictures + momentoes of home, and some type of small filing rack for all the papers for different classes. Of course, what you bring depends on you, but try to bring something that's YOU and can be a conversation starter if people walk by or drop into your room. You'll get to meet a lot of people this way.
Secondly, you may also wonder how you're going to lug your new mini fridge up three flights of stairs. That's where the Greeters come in. On move in day, you'll see students dressed in orange shirts with a nametag on the front that says "Hello, my name is [blank]". Grab one of them and they'll happily point you to the right building or lug up your suitcases. I was a Greeter the move in day of my second year -- a lot of people do it because you get to move in a day early and beat all the move in traffic and general noise and congestion. When it was time to do my Greeter duty though, I almost wish I hadn't signed up. Ladies and gents, that day is HOT. Come in tanks and shorts, you can change into more presentable stuff later if you want. I would say come in as little clothing as possible but not being obscene. In between trips to the car, the sun beating down on you, going up 10 thousand flights of stairs into unair-conditioned areas.. you'll want to die. =P
