Big H , your're right about "single man tent" does sound a bit pitiful, but I hiked the length of Cumbria once with a "family" tent and it was sadder still waking up with all that space around me,must have looked like the rest of the party had buggered off!. There's still enough scratching space though in the "oner" as its tallish.
Only need somwhere to put it, as I'm getting the train this year I'll be a "walk on" I've tried Houx previously, but this year I fancy going for MB, how much space is there likely to be when I arrive at 9pm on Thursday?
About knock out gas , and over imbibing, Absinthe knock me out very sharpish, not that I'll be havibng any of that in Le Mans.
