The LEGO Batman Movie came out this year. I decided we needed to add some batman to the yard. I chose the speedwagon from the movie as it was the most used vehicle by Batman. It was built from the model at a 1" to 1' scale making the replica about 12 feet long and 6 feet wide. My kids could sit in the seat built in and do a photo op. They seemed to like it, so much they were Batman and Bat Girl for Halloween. Both costumes made by Grandma Holly.
A full instruction set to build your own if you really want to is found here.
We went to East Harbor State Park again this year for the first weekend. We took home first place for the electric camp sites. It was a blast. We showed the LEGO Batman movie with a projector and a 120 inch screen. I used the sound system from my display to power it. You could hear it from 3 rows of campsites away.
