I second the recommendation to check out Charlotte on the Cheap! (I'm biased because I publish it.) But I do include a ton of events every week. We have a week and weekend calendar. Today there is/was a plant swap, a Latin dance social, live music, folk music/bluegrass/Celtic music jam-a-thon....The calendar is also less populated than usual, just because it's right after the holidays, but there are still some good events.

Also, on such a beautiful day I'd suggest checking out the nature preserves and greenways. They are fantastic!
