Going to see my girls

I'm going to surprise Katelyn (age 15) and Jillian (age 9) with a visit to Colorado Springs.  Katelyn's birthday party is Friday night and I can't decide if I will just walk downstairs and surprise them or call her on the phone and say "come upstairs."  Either way, I'm so excited to see the girls and spend time with Shannon.  I love that whole family.
