Legos are a big deal, but not for the faint of heart. It's a dangerous business playing with legos.
It doesn't matter how well you think you cleaned up the mess... there's always one more lurking in the carpet... waiting for a bare foot to come along.The other thing about legos is that there is no such thing as too many. Gavin has a really nifty storage unit for all of his legos. He's very carefully sorted them all by type and assigned a bin for each kind of brick.
Each set comes with a very detailed instruction book. It's fun to watch Gavin with the booklet open before him, as he intently searches for the correct piece to assemble his new favorite toy.
