Who’s to blame for a vacation from hell? In the case of Robert and Nicolette Sumner, the San Jose couple whose plight was described Sunday by Tribune columnist Bob Cuddy, there’s plenty to go around.

First, a recap: The Sumners thought they had booked a peaceful, beachfront retreat in Oceano — a house where they could stay with their three small dogs — but instead wound up staying near the entrance to a noisy off-highway vehicle playground.

Their vacation, they say, was ruined, and they sent a letter to several state and local officials that described just how dangerous this area can be to pedestrians.
