Do you like to rake all the twigs and leaves off of trails? I have noticed this is the only thing that slows down water flow. Water very quickly erodes trails. Let the leaves stay. These become the new loam that protects the dirt.
I like riding loamers.
I am not a fan of flow trails. NSMBA does a spectacular job of water diversion. They are experts on building trails that will last with minimal maintenance. . So go ahead rake those flow trails.
In the case of loamers/Duff trails. The less you do to the trail the longer it will last.
common sense…..Whats common about sense?!
