APB-going south along I5, Explorer with three teenage boys

My brother and his two friends are currently MIA on their way down to Seattle for the Enumclaw Highland Games. They left 8 hours ago, then got pulled over for missing a single lugnut on their car. It got towed and they were left at the side of the freeway. They made it back to our house, then left again, using a different car. This was about six hours ago. They should have made it to Seattle by now and met up with my dad, who has been phoning us every half hour for the last two hours.

My mother is starting to get very worried.
