Now maybe I'm cheating a little with the trailer, but I get some of the biggest reactions from the kids. They have grabbed a hold of mom or dad and said stuff like "Wow, look at that!!!" I will let them sit in the trailer and let mom or dad take pictures.
I had two little girls at one cruse that had to go get mom so she could see it too. When they came back we let them sit and mom took pictures. They just loved it. And it's a lot of fun to see the little ones just jaw dropped and stairing at the combo like it was from outer space or something.
Now imagine the kids reaction if they saw your Challenger trailer and you sold icecream out of the back of it!!!!!
