Why Hillside to Hollow Reserve dries this way

Hillside to Hollow Reserve is a mountain bike network in the Boise region of ID, riding on sandy soil that drains fast over terrain that drains at an even, moderate pace. With little tree cover, sun and wind get to the dirt fast. What really sets the timing here is how quickly that ground gives back a firm, dry surface, not what the day’s forecast says. The SW-facing aspect gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture, and the rolling terrain, about a 6.9° average grade at 2,966 ft, drains steadily rather than pooling.
