Ok, I'll admit it. I am one of those guys in his 30s who still plays with Legos. Or I should say, rediscovered Legos about the time the Viking collection came out. I sold my Legos when I was in high school and was always sorry I did. Legos open up whole worlds...Heck from what I've seen...they open up whole universes. Their is no limit to what can be done with a few plastic bricks, a some minifigs, a little imagination, and a little (or a lot) of patience.
