All of my kids loved Legos, girls or boys. Had big bins of them in different sizes. When their cousins visited, it was insane! Legoland had nothing on us! I love them because it allowed them to use their creativity when they were building on their own as opposed to using the kits.
When we graduated to the Ferris Wheel and it moved? Holy Moly! We suddenly graduated to moving pieces. That was a blast.
I don't think you could have gotten anything better, being age appropriate and all. :)
You are a great uncle and he is going to love it!
I got a lot of second-hand ones at Salvation Army and places like that!
Lego has been a part of so many people's lives from kids playing with it, to parents stepping on it - The worst pain imaginable in the world. Lol.
I've been hitting some second hand places to see what I can find and haven't been able to pick anything up yet. I've got some time though and will continue the search.
