By Colette Zaborniak, MAC communications dept.   There’s something to be said for celebrating a decade. When you turn ten, it’s a big deal – you’re finally a double digit! And hey, being a single digit for 9 years can get pretty dull. So you can imagine Mesa Arts Center is pretty excited to be celebrating the tenth year at One East Main Street! Although there won’t be cake and presents, or Aunt Jill pinching your cheeks remarking on ‘how grown up you are’, there’s a lot more to celebrate at this year’s Season Kickoff Festival .
