Drumlanrig has always been an individual charge for use of the facilities. If you park outside all you are doing is jeopardising the development of the trail network.
Drumlanrig is as far as I know the only trail centre in the UK which is completely stand alone and sustainable, having not benefitted from massive public funding or grants funded from the tax paying public.
None of the trails would exist without the charge at the gate so if you want to ride there pay up or go somewhere else please.
Those that park at the bridge are always noted and when the ranger service that I work with in partnership on the trails try to justify new trails to the powers that be, it’s the free loading cheapskates that get brought up time and time again.
Seriously if you don’t want to pay a fiver for a whole days riding on great natural feeling (but totally manmade) trail: then either buy a season ticket, join the Drumlanrig/Rik’s Bike Shed club and do some trail maintenance days or p1ss off somewhere else where you’re not spoiling all my hard work thank you very much.
