First off, great post Tim! I agree with almost every point. I think this could be down to accessibility? I know that before I drove, it was really hard to get around to ride new spots/natural venues - relying on parents for lifts (who have nothing to do for 4-5 hours unless they are interested in trials too, hardly appealing to them!)... On the flip side, a train journey lands you in the middle of a city/town and you have riding within a few minutes. My guess is that the average age of 'street' riders (people who usually ride street) is much lower than that of 'natural' riders. I reckon this is for a few reasons but one of the main ones could be travelling issues. Every rider I know who has had the chance to ride a quality natural spot in decent weather with good company has LOVED the challenge, the almost instant progression in their riding and the stress-free atmosphere (no security!)... Anyway, bit of a tangent there, but I look forward to seeing other's replies Nice one!
