Smooth driving and lots of flowers after a rain storm the day before. You can drive fast on this road but what's you're hurry?

This trail is fun and high speed, nicely graded surfaced with 2" or smaller gravel. there are occasional washes to watch out for but otherwise a great road to travel on, stock suv/crossover should be fine, might be spicy crossing the small washes in a sedan after the rainy season.
