Because of this bad memory from the first and last one we attended in 2011.
Since this is Gracie's last year at MES (and Thomas' first and last) we sucked it up and went as a family.
While, the kids had fun, I have to say that it was kind of "puny" by comparison to year's past. I think we did everything there in 1 hour.
But, like I said, the most important part was the kids having fun, and they seemed to have plenty of that.
