Today was Make-A-Wish's Walk for Wishes event at the Great Park, in Irvine CA. The park's centerpiece is a large orange helium balloon that takes visitors for rides, although during the event it was too windy for the balloon to go up.
R2 arrived incognito around 7:30am.
At 8:00am the event started, and the characters mingled with the crowd. Some pics.
Someday you'll get to ride up in the balloon R2. (Or not.)
