I don't know that I'd ever want to attend
CivicFest.
Apparently many people here would agree.
The festival is entitled "A Very Minnesota Celebration" and features exhibits and a marketplace. It is centered around Minnesota and U.S. history.

The original admission cost for adults was $15. Now, the Star Tribune is reporting that admission is "free" but suggests a donation with proceeds going to Hurricane victims. Why they didn't think of that in the first place? However, it is celebrating America, so following suit with the way Americans would rather throw money at something than volunteer their time seems appropriate.
I did find it interesting that the political buttons seller wasn't doing so hot (seeing as how you can go a few more miles and probably find them everywhere at the RNC) and the person selling books about the economy wasn't doing well (because when the economy isn't great, why not buy books about it!).
Furthermore, after twelve days of the Minnesota State Fair (where attendance was excellent), who wants more concessions? And after so much coverage of the RNC, protesters and presidential nominees, I'm not sure I know of anyone who wants to celebrate America too much more.
I must say this is maybe not the best timing for an event like that. It looks like an event on a rainy day with nothing better to do.
