if you ride every weekend at Back Cowm, yes it can add up to a few quid but there is over 100 acres to ride on, and a tenner aint much when you put a least a grand down on a half decent bike and put 20 quid in the van/car to get there and five in the bike to ride
i havnt been to back cowm quarry in aaaaaaages because of the huge price increase and neither have my mates, the only time i will go back cowm quarry is a day when its not too hot and not too cold, the perfect temperature and i will get there for the 9.30 opening and i will go at sun down, i think that this is the only way to get your moneys worth at back cowm, or as you say ride more comps
