I-15 with young children

Thanks, a nice blog. As mentioned we've traveled that way before, just not in recent memory with young children. Red Rock Canyon East of Las Vegas is a nice turn out for an hour or so, or you can follow the road all the way back to Las Vegas. Indian petroglyphs and lots of ground squirrels. I remember an Indian museum north of St. George just of the freeway. The Island at Salt Lake City is a fun day but hard to find as only one road through a residential area give access. I'm still watching to see if others respond with ideas.
