The family at the gas station said they were headed to Vancouver to check on property. It is probably likely they were headed to Vancouver, BC but I found it odd that they didn't specify since the main interstate coming from California is I-5, which goes right through Vancouver, WA. If it was Vancouver, WA, they were already way too far north, but maybe they decided to visit Mt. Rainier while they were in the state? (I live in the state, so know my way around)
