Sure, Sweetie!

1. I went to the State Fair last summer.
Possibly might say I attended a judicial hearing, but definitely my most nat. usage is I went to. I prolly wouldn't say I attended a Louisville Orchestra concert most of the time, though it would be my second choice.

2.You finally made it.(to a friend)
I was beginning to worry that something might have happened to you. (to an acquaintance--sorry, I could not bring myself to add "to make you so late"--I know you asked for those words.)
