Contest: Write to Win
Hosted by: Legoland Discovery Centers
Description/categories: This one is just for the kids (sorry, AFOLs). I've linked the rules for the Legoland Discovery Center in Chicago, but they also have the same contest running at the Dallas/Fort Worth Legoland Discovery Center, so I'll assume the same contest is running at all of them (or at least all of them in the US). Kids 12 and under can win a family annual pass to the center for writing the best things to do in the Chicago area (or Dallas/Fort Worth, or presumably wherever any of the LDCs are), what makes a great birthday party, or five LEGO building tips. Winners will be chosen by votes on their Facebook pages. I don't see any residency requirement, so I'm guessing you could enter more than one of these (say, for example, you live in Oklahoma and could reasonably travel to both the Kansas City and Dallas centers).
Deadline: July 11
