Bus/Combi/Camioneta to Playa Troncones

It's been 2 or 3 years since our last daytrip to Troncones. Walking any distance is out:
- Does the La Union bus still stop along the highway, for Troncones?
- Do we wait there, at the drop-off point, for a camioneta to the beach?
- If no camioneta shows up, do Troncones taxis routinely check for people waiting at the drop-off point on the highway?

(We recall, several years ago, having to walk down the hill from the highway drop-off, past the Pemex station, down to the old stop on the old highway, before any collectivo ever showed up. Unfortunately, we can't do that walk any longer.)
