So i was just thinking about Lego's and K'Nex. i'm sure most of us have all played with Lego's or K'Nex or both. It's been a while since i had mine. i was more of a K'Nex guy, i had about 5,000 pieces, not so much into lego's. Whar are you guys into? i used you build all these cars that had suspensions and four wheel drive. it was lots of fun, i really liked it. helped to shape me into my engineer visions of today. i would try to copy suspension types in order to make mine. any of you guys do this? which was your favorite type and what did you build?
