anyone traveled across CANADA/ US border customs by bus?

how long did it take, do they go through the whole bus? i need to know how it's going to delay my trip. do they have to go through all the luggage on the bus?
anyone who has actually experienced this please let me know how it went down. thanks

it depends
sometimes they will go through everything and everyone but sometimes they won't
sorry, I know that this is not a very definitive answer but that is the way it is at the border

I have and it didn't take very long. They came on the bus and asked where everyone was from. I couldn't see if they went through the luggage or not. Took about 15 mins total. Granted my trip was pre 9-11 so things may be a little different now.
