So I don't know how I am only just finding this photo now, but I love it! Thanks Chinmay for posting it! To answer your question, out of the people in this picture we probably have about 36 years of experience. The FIRST magicalness started for our family all at the same time when I was in 4th grade with Lego League. My parents ran a Lego League team in our basement for my brothers, me, and some other kids from our neighborhood. From there, we were all hooked on robots.
Dave, reading your post absolutely made my night. That was one of the nicest things someone has said about our family. Now don't short change yourself because you and your family are pretty awesome too! Just goes to show that families that build robots together, stay together.
