Definitely a willy waving contest on most. And if you have anything considered poverty spec then they generally ignore you or point N laugh
In terms of reviews of where to ride I find you go to local places and other riders will talk to you...giving hints about new routes etc. plus they ride often so the bikes ain't all DH monsters...I find most DH riders the ones up their own arses and intimidating. It's that get out of the way attitude
