I truely envy you. (mostly for the United States visits)
I've wanted to visit San Francisco since I'm eight, but never made it...
Actually my former school always made trips with 6th grade classes to London or other cities in England, but my class didn't, the reason was, that my formmaster was afraid of a terroristic act, so we traveled to Prague....Sad story^^
Other topic:
Which english books have you read so far?
In school I 'had to' read:
Katie.com (very good book)
Oliver Twist
A Christmas Carol
Snow Falling on Cedars (this one was pretty hard to read, many unknown vocabulary)
Quest for a father..and some more I can't remember now^^
At home I often read english books to keep my english ,up to date'.
I've read the Monk books, which were easy to read.
Twilight and New Moon (also easy, sometimes too easy...)
and I've read the last two Harry Potter books in english, they weren't easy for me, too many unknown vocabulary...but I have my dictionary
