Should We Stop at Mema's?

74 miles and counting. We're getting on I70 in Breezewood. The kids are definitely wound up. I tried to talk Tom into stopping at the Starbucks drive thru we just passed but he kept driving. I guess I won't be going for 4 coffees in one day. Anyone think we should stop at Mema's house when we pass by? It'll only be an hour or so after her bedtime. Surely she'd be happy to see us, right?
