UPDATE: Reviews section refreshed, redesigned, searchable: Go take a look
Has anybody done this? Watched the stage videos on here, looks like a pretty good way to ride BC. Might get an entry in for next year.
it looks great - of course I have not done it, but have been interested for a couple of years now.
You will need to book well in advance - early bookings sell out very quickly, so when I think when/if I finally take the plunge, I will try and book 1+ year in advance to get the cheapest entry/plane ticket possible.
You could buy the current mag and read about it?
A couple of the guys in my team did it this year - one posted day by day here:
Mega, out the country for another week but ill but the mag when I'm back so long as it's not been replaced. Pretty keen.
