We live over by Hayden Lake. A car or two go in the lake every year. They changed the entrance to the boat ramp so it’s no longer right at the end of the road, but people STILL find a way to drive into the lake. Yes, alcohol is usually involved.
I remember that one, if we’re talking the same one. South side of the lake near Honeysuckle Beach? That might have been tricky even for a sober person if the visibility was bad or the driver was inattentive. Even if we’re talking about different sites, there were lots of opportunities on the lake road for careless drivers to find the water with their cars. Like Fernan Lake, in most places, Hayden Lake gets deep really quickly.
