Our father's day outing at Folsom Lake.  Although it was June, it was not a very warm day for swimming so most of the kids stayed out of the water.  So, instead they spent their time building stuff in the sand.  You'll see after a while, the kids started building a fort with a dam.  They all helped build it, fill it, and then break it.My brother-in-law, Sinh, brought his speed boat and all the kids took turn riding it.  Then the kids had fun playing duck-duck-goose.
