Subject: Strip is not stripping trailing whitespace

I have files with city names which have one or two trailing whitespaces:

Adelanto  <-
Agoura Hills  <-
Alameda  <-
Albany  <-
Alhambra <-
Aliso Viejo  <-

My method just iterates and strips!

def trim(state)
  diskfile = File.new(state + "-cleaned.txt", "w")
  $stdout = diskfile

  IO.foreach(state + ".txt") do |line|
    line.strip!
    puts line
  end

  diskfile.close
  $stdout = STDOUT
end

The output successfully removes leading whitespace but not trailing
whitespace.  What am I doing wrong?  I would chop! but the number of
trailing whitespace characters varies and my attempt at a while loop to
check and chop! was unsuccessful.
