another tip taken for granted... when crossing narrow bridges, don't look at your front wheel look ahead at where the bridge goes.. this way you will go straight. never thought much of this until they painted the parking lot at the trail head and I tried the white line test.

if your on the side of a hill.. dismount to the uphill direction.. this tip borders on common sense, but I've seen folks go down this way or get personal with their top tube..

also momentum is the key on up hill small logs or medium rocks. pedal hard before you get there then stop pedaling get the front wheel over and then pedal again to avoid pedal/ foot strikes..

mountain riding is like a chess game you have to think several moves ahead,
