Speaking of Nogaro 100pc have an offer posted on Visordown here
http://www.visordown.com/forums/showthread.php?t=206757 for £199 for 4 days on track in September and £99 for bike transport to the place.
Not a recommendation from me but that seems staggeringly cheap... It's gutting 'cos the next week I'm staying 50 miles away from there in a villa and it'd be perfect...
