You take the family out to Wonderland. Sure it might rain but many times when we have a decent chance we end up with not a drop. I get it. Plus it might be a night that your work planned their company picnic. You don't want to miss the fun.
Wonderland Park is somewhere I think we all grew up at. I know I loved going as a kid when I moved to the area back in 1986. I spent many nights there in high school too. Once my daughter was born I couldn't wait to introduce her to the rides.
