chairlift = basically no cues
i think the main reason behind it is safety, as all of the things that mtba do. i assume that there have been younger riders mowed down by older ones while they stand in the middle of the track right after a fast blind corner, which pisses both ridersoff. this will stop those sorts of incidents from heppening. i think, if you look at it the right way, that it could make practice more fun too, you just have to find those who are in your category (will not be hard) and do chain runs etc. - chain runs in an open practice session can piss off many of the slower riders, but in seperate prac times it won't be as bad...
i'm just trying to be optimistic here - i'm sure that you'll still have shitloads of fun and feel like you can't move after the weekend is over.
