I Will get there as early as is practicable and reasonable , definitely before 9.30..... how much before depends on what time I get to bed friday night... Working late sadly.... not drinking .
If it's necessary, although I'm not really local, there's space for a tent or maybe two, on our garden...... I am however, some distance from Brackley....
I'll bring my idiot 15 year old Son with me to assist in making of tea, butties , burgers , and the like .
Sadly, while he's usually really very good and helpful crawling into small spaces and getting hands into even smaller ones, with utterly typical teenage stupidity, he's broken and badly torn the ligaments of the middle finger on his left hand, and is of course, left flippin handed... so generally willing but not entirely able.... but he does have a wicked sense of humour and does a pretty good line in improv comedy.....

I'll drop down to the Market in Oxford tomorrow and see about some bulk deals on dead animals for a contribution the BBQ.
