LEGO are cool just to play with at our age. I still have all of my LEGO from when I was a kiddo and still get them as gifts sometimes.

My brother-in-law is a Huge LEGO flipper. He lives in Australia. So LEGO there generally cost a lot more to acquire than they do here in the US. But he finds them at garage sales, and flea markets then puts the sets together to sell (if they aren’t in their original boxes.) Sometimes he gets us to bring him stuff from the US that isn’t in Australia, and he sells that too!
