Do dollars reach MtGox through other channels than Dwolla? There've been some questions here about MtGox getting dollars through Dwolla, but what about other channels besides Dwolla?  Are dollars still reaching MtGox somehow?  The price of BTC on MtGox a few minutes ago was over $131, up a bit from a few days ago.  There must be dollars there for people to bid with, and buy bitcoins with; otherwise this couldn't happen.

Another thing I've wondered about is transferring dollars straight to a bank account in the USA.  International bank account numbers are not used in the United States.  Is there a way to do it without one of those?
Yes, you can transfer cash to Mt.Gox using a service like BitInstant.
