Here for rides.
In Surrey it is traditional to follow them back to the car park, and if they load their Santa Cruz full boinger into an Audi, just keep riding.Also, if you see other riders that look skilled and not on a strava mission, you could ask them their technique.
I have seen a few a-holes on the trails but generally most people are cool and will help out if they can. They can only say yes or no.
