Just out of interest,
If sproxton is a no go would the same amount of enthusiasm abound for a semi wild camp out,??
I don't mind, except that if it's pissing with rain, it could be fairly cold and miserable sitting out, possibly under your tarp (if you're taking the van), enough chairs etc., and plenty of drinking water.
I'd say more of a Spring Summer Autumn thing than late November.
If the CC is not up for it, let's look for a venue with a pub/campsite combo, or a campsite that won't mind a bunch of us turning up. I'll start looking for alternatives just in case.
