# IMPORTANT: To create a bucket in the default us-east-1 region,
# do not add the LocationConstraint.  Adding a LocationConstraint of "us-east-1"
# causes an error "The specified location-constraint is not valid."
# By default, the bucket is created in us-east-1 by sending a PUT with an empty body.

# In this case, the bucket name is "chilkateuwest2".
