They ruled the earth some 65 million years ago, and now they're back to take over the Wisconsin Center.  For this weekend only, you can see the "Discover The Dinosaurs:  Time Trek" exhibit.  The pre-historic adventure will certainly have your kids' attention with all the interactive activities.  But the big draws will be the baby dino, T-Rex, or rhinoceros. 

There's another section of the exhibit dedicated solely to sharks since some of these fish were around even before the dinosaurs.  Again you only have two days to see this attraction, Saturday and Sunday.  Click here for times and ticket prices.
