Jupiter is currently building the Ecto 1 thanks to Grandma Ernie and Grandpa Pat. I am really loving these LEGO Ideas sets. I applaud LEGO for bringing community involvement to their retail products. I am sure it is no easy task as there must be licensing hoops to jump through as well as making sure the products meet a certain degree of structural integrity. The Back to the Future set was equally fun to build. One thing that I really like is that, aside from unique paint on some of the pieces, these all seem to be built from preexisting pieces. There are seemingly no new molds created because, for example, a certain Star Wars vessel has some particular need. Maybe one day we can submit one of our own creations to LEGO Ideas to be voted on as a potential product, but for now we have been more than satisfied with what the community has come up with. Now if only we had some of that Hi-C Ecto Cooler that I loved drinking in the late 80s, we could really get the nostalgia flowi
