As a kid, I didn't play with LEGO a lot. When I got the opportunity I'd try to build houses or Voltron (I'm a product of the 80s).
My son is now into LEGO - and now I think I'm more into it than he is. I think I'm into it more for the challenge of creation. As a software engineer who is more architect and manager than hands-on, this hobby fills a need.
I remember as a kid visiting folks who were train hobbyists and going into their basements where their set up was and being amazed at the details. This wasn't LEGO - but nowadays with LEGO it can be... so I have dreams. :)
I have my MOCs here, but I also have a LEGO blog on tumblr. Take a look.
