Red or blue? How do Frans and Allison van Riemsdyk dress for nights like these? “Usually they’re wearing both colours,” says James van Riemsdyk, 28, the eldest of the family’s three hockey-playing sons. The two-thirds of the van Riemsdyk boys who have already realized their NHL dreams are set to face off against each other Thursday night at Air Canada Centre, as James’ Toronto Maple Leafs take on Trevor’s Carolina Hurricanes. Frans and Allison have been in town since Monday anticipating tonight’s sibling showdown — the first since Trevor was traded to the Eastern Conference – and will stick around for James’ match Saturday versus his former club, the Philadelphia Flyers.
