I've seen the word challenging a few times on this thread the marketeers have got some of us good and proper.
I like to have a little tear down the double headed dog or deliverance and the odd jump and stuff but for me the real fun is riding wheel to wheel with my mates down some flowy singletrack at high speed getting the odd little bit of air here and there, Barrys and most of the sanctioned trails give me that buzz every time.
I am always pleased with myself when I ride a proper steep roll in hanging off the back or drop off a few feet somewhere but I suppose deep down I'm just a XC jeyboy!
The great thing about BKB and many of the others is that anyone can ride them and they get more fun the faster you go, I think the builders have done a great job. Sanatised? I don't think so, over used, probably..
I know there are people who want the thrills of huge jumps, big drops and all the rest, sometimes I'm one of them and it's all available within 30 mins ride of BKB if you know where.
Cocking up one of the most used trails is just not on, end of. As for people treating it like a mini DH track – HA!
