Fall in BC brings back rain. Rain brings saturated green vibrant moss, ferns, evergreen and decidous trees back to life. Roots, rocks and rolls get a bit slippery but that keeps one honest. The trails that become a bit brown and dusty when dry and easier to ride for the tourists visiting in summer become a bit more challenging and you have to re-learn nuances you might have forgotten. Little tricks that save you from faceplanting, endo'ing, tomahawking resurface from your mental harddrive. It's a fun time to ride.
